Problem: Clicking on window separator in statusline crashes Nvim due
to out of bound memory access
Solution: Check if the click location is within clicking range before
applying it.
Problem: Diff mode's inline highlighting is lackluster. It only
performs a line-by-line comparison, and calculates a single
shortest range within a line that could encompass all the
changes. In lines with multiple changes, or those that span
multiple lines, this approach tends to end up highlighting
much more than necessary.
Solution: Implement new inline highlighting modes by doing per-character
or per-word diff within the diff block, and highlight only the
relevant parts, add "inline:simple" to the defaults (which is
the old behaviour)
This change introduces a new diffopt option "inline:<type>". Setting to
"none" will disable all inline highlighting, "simple" (the default) will
use the old behavior, "char" / "word" will perform a character/word-wise
diff of the texts within each diff block and only highlight the
differences.
The new char/word inline diff only use the internal xdiff, and will
respect diff options such as algorithm choice, icase, and misc iwhite
options. indent-heuristics is always on to perform better sliding.
For character highlight, a post-process of the diff results is first
applied before we show the highlight. This is because a naive diff will
create a result with a lot of small diff chunks and gaps, due to the
repetitive nature of individual characters. The post-process is a
heuristic-based refinement that attempts to merge adjacent diff blocks
if they are separated by a short gap (1-3 characters), and can be
further tuned in the future for better results. This process results in
more characters than necessary being highlighted but overall less visual
noise.
For word highlight, always use first buffer's iskeyword definition.
Otherwise if each buffer has different iskeyword settings we would not
be able to group words properly.
The char/word diffing is always per-diff block, not per line, meaning
that changes that span multiple lines will show up correctly.
Added/removed newlines are not shown by default, but if the user has
'list' set (with "eol" listchar defined), the eol character will be be
highlighted correctly for the specific newline characters.
Also, add a new "DiffTextAdd" highlight group linked to "DiffText" by
default. It allows color schemes to use different colors for texts that
have been added within a line versus modified.
This doesn't interact with linematch perfectly currently. The linematch
feature splits up diff blocks into multiple smaller blocks for better
visual matching, which makes inline highlight less useful especially for
multi-line change (e.g. a line is broken into two lines). This could be
addressed in the future.
As a side change, this also removes the bounds checking introduced to
diff_read() as they were added to mask existing logic bugs that were
properly fixed in vim/vim#16768.

Problem: Error messages that cause a vim.ui_attach() namespace to
detach are not visible in the message history. Decoration
provider and vim.ui_attach error messages are dissimilar.
Solution: Emit vim.ui_attach() errors as an actual message in addition
to logging it. Adjust error message format.
Problem: Message kind logic for emitting an error message is convoluted
and still results in emitting an unfinished message earlier than
wanted.
Solution: Ensure emsg_multiline() always sets the kind wanted by the caller
and doesn't isn't unset to logic for emitting the source message.
Caller is responsible for making sure multiple message chunks are
not emitted as multiple events by setting `msg_ext_skip_flush`...
Problem: Reconfiguring a float window applies the global 'winborder'.
Solution:
- Ignore 'winborder' when reconfiguring a float window.
- Still apply 'winborder' when converting a split to a float window.
Problem: Paired mark whose end is in front of its start should not have
its decor removed (as fixed by 72f630f9), but may still need to
have its range redrawn.
Solution: Still call `buf_decor_remove()` but ensure it is not called with
an inverse range when `extmark_del()` is called on an end mark.
Problem:
There is currently no global option to define the default border style for floating windows. This leads to repetitive code when developers need consistent styling across multiple floating windows.
Solution:
Introduce a global option winborder to specify the default border style for floating windows. When a floating window is created without explicitly specifying a border style, the value of the winborder option will be used. This simplifies configuration and ensures consistency in floating window appearance.

Problem: Marks that go beyond the end of the buffer, and paired marks
whose end is in front of its start mark are added to and
removed from the decor. This results in incorrect tracking
of the signcolumn.
Solution: Ensure such marks are not added to and removed from the decor.
Problem: Virtual 'statuscolumn' lines are evaluated with a misleading v:(rel)num.
Namely set to the line above for `virt_lines_above = true` lines, or even
the last drawn line for a partial redraw.
Solution: Set `v:lnum` for the first evaluated row of a line, first above
virtual line of a row and first non-virtual line of a row.
Problem: No block events emitted with ext_cmdline for :if, :while, :try etc.
Solution: Emit cmdline block events; store the indent level of the
previous cmdline and whether a block event was emitted.
Problem: Various list commands end in a newline to go to a new line on
the message grid for the prompt message, which is unwanted
with ext_messages.
Solution: Don't emit a trailing newline with ext_messages for
inputlist(), :tselect and z=.

Problem:
"use_float" in the if-condition causes a new buffer to be generated on every execution.
Solution:
- Remove the incorrect use_float check from the condition.
- Use buf_clear to properly clear the existing buffer.
Problem:
1. The original info text is truncated in pum_set_preview_text.
2. There is an extra newline character at the end of the info text.
3. Incorrect usage of plines_win leads to errors in calculating the window height.
Solution:
1. Improved string handling in pum_preview_set_text to safely process line content without modifying the original text. Now, the preview info is correctly preserved while splitting lines.
2. Do not append a trailing newline to the preview buffer when one is present at the end.
3. Set w_widher_inner in advance; otherwise, plines_win cannot correctly calculate the wrapped line height.
Problem: Skipping over a concealed line for which `win_line()`
_should_ be called because it has `virt_lines_above = false`
lines associated with it.
Solution: Don't include such a line in `wl_lastlnum` from the line
above.
Problem: wildmenu highlighting in popup can be improved
Solution: Check if the completion items contain submatches of the
entered text (Girish Palya).
This update enables highlighting in the popup menu even when the matched
fragment or pattern appears within an item (string) rather than only at the
beginning. This is especially useful for custom completion, where menu items
may not always start with the typed pattern.
For specific use cases, refer to the two examples in
https://github.com/vim/vim/pull/16759
A sliding window approach is used with direct string comparison. Performance
is not a concern, as highlighting is applied only to displayed lines, even if
the menu list is arbitrarily long.

Problem: Cannot use "g<" mapping with ext_messages. Mapping displays
the scrollback buffer since the last command, but the
scrollback buffer is not populated with ext_messages.
Solution: With ext_messages; store messages in the history that otherwise
wouldn't be. Mark them as temporary messages to be deleted when
the scrollback buffer would be cleared. To this end, make the
message history a doubly-linked list such that messages can be
removed from an arbitrary position.
Outlook: Default ext_messages UI might not show the hit-enter prompt
so we want "g<" to work as a recommended way to show messages
for the last command (prompted by an indicator).
Problem: Vim's diff block merging algorithm when doing a multi-file diff
is buggy when two different diff hunks overlap a single
existing diff block (after v9.1.0743)
Solution: fix a couple bugs in this logic:
1. Fix regression from v9.1.0743 where it's not correctly expanding the
2nd overlap correctly, where it always expands without taking into
account that this was always taken care of when the first overlap
happened. Instead, we should only grow the 2nd overlap if it overhangs
outside the existing diff block, and if we encounter a new overlapping
diff block (due to overlap chaining).
2. When we expand a diff block to match the hunk size on the orig side
(when handling the first overlap), we expand the same amount of lines
in the new side. This is not sound if there exists a second overlap
hunk that we haven't processed yet, and that hunk has different
number of lines in orig/new. Fix this by doing the corresponding
counter adjustment when handling 2nd/3rd/etc overlap by calculating
the difference in lines between orig and new side.

Problem:
popup floating window is closed and recreated for each item selection,
this is a bit wasteful.
Solution:
- Hide the preview win (instead of closing it) when the menu is still displayed:
1. When selected_item is -1.
2. When switching from an item with an "info" field to one without.
- When pum is undisplayed it is still closed.
Problem: f58e7d5f passed `&botline` to `plines_win_full()`, (probably)
assuming it would be set to the first line of the fold.
Solution: Reinstate call to `hasFolding()` to do so.
Problem:
Indenting text is a common task in plugins/scripts for
presentation/formatting, yet vim has no way of doing it (especially
"dedent", and especially non-buffer text).
Solution:
Introduce `vim.text.indent()`. It sets the *exact* indentation because
that's a more difficult (and thus more useful) task than merely
"increasing the current indent" (which is somewhat easy with a `gsub()`
one-liner).
Problem: When expanding omni completion items with newlines (e.g.
`then\n\t\nend`), the end statement gets wrong indentation.
Solution: Add OPENLINE_FORCE_INDENT flag to make open_line() use
second_line_indent directly (glepnir)

Problem: setting title and/or footer without explicitly setting border
shows "title/footer/ requires border to be set" error.
At the same time, explicitly setting `border = "none"` (which is
default) shows expected no-border-no-title-no-footer window without
error.
Solution: allow setting title/footer without explicitly setting border.
Problem: No kind for `:registers/autocmd/augroup` messages. `:registers`
chunks are emitted as separate `msg_show` events.
Solution: Add the `list_cmd` kind to the message. Introduce a new
`msg_ext_skip_flush` variable to set to true around a
group of to be paired message chunks.
Problem: Messages preceding a `cmdline_show->prompt` event can not be
distinguished as such when receiving the event. (But since
`msg_show` handlers should be scheduled, one can already check
whether a prompt is active when displaying the message.)
Solution: Rather than add a new kind again, use the `confirm` kind.
Could be seen as slightly misleading where it is more of
a choice rather than a confirmation, but that already applies
to `confirm()` as well...
PuTTY sets TERM=xterm, but sends ESC[1~ and ESC[4~ for Home/End keys,
which does not match what the 'xterm' terminfo has for khome/kend, so
libtermkeys instead reports them as the original DEC VT220 names.
The VT220 came with a DEC LK201 keyboard which had the following keys in
the area above arrow keys (where PCs now have Ins/Del/Home/End/etc):
┌────────┬────────┬────────┐
│ Find │ Insert │ Re- │
│ │ Here │ move │
├────────┼────────┼────────┤
│ Select │ Prev │ Next │
│ │ Screen │ Screen │
└────────┴────────┴────────┘
These would send ESC[x~ sequences in the expected order:
┌────────┬────────┬────────┐
│ ESC[1~ │ ESC[2~ │ ESC[3~ │
├────────┼────────┼────────┤
│ ESC[4~ │ ESC[5~ │ ESC[6~ │
└────────┴────────┴────────┘
Modern terminals continue to use the same sequences for Ins/Del as well
as PageUp/PageDn. But the VT220 keyboard apparently had no Home/End, and
PuTTY apparently chose to re-purpose the Find/Select key sequences for
Home/End (even though it claims to emulate Xterm and this doesn't match
what actual Xterm does).
So when Home/End are used in Neovim through PuTTY with TERM=xterm (the
default setting), libtermkey finds no match for the received sequences
in the terminfo database and defaults to reporting them as <Find> and
<Select> respectively.
PuTTY is not unique here -- tmux *also* sends ESC[1~ and ESC[4~ after
its internal translation -- but the difference is that 'tmux' terminfo
correctly maps them to Home/End so Neovim recognizes them as such, while
PuTTY defaults to using 'xterm' which uses a different mapping.
This initial patch only allows Neovim to recognize <Find> and <Select>
key codes as themselves, so that the user could manually map them e.g.
using ":imap <Find> <Home>".
Alternatives:
- Using TERM=putty(-256color) would of course be the most correct
solution, but in practice it leads to other minor issues, e.g. the
need to have different PuTTY config profiles for older or non-Linux
systems that lack that terminfo, or tmux's insistence on rendering
italics as reverse.
- Using Neovim through tmux avoids the problem (as tmux recognizes
ESC[1~ on input), but is something that needs to be manually run
every time.
The keycodes.h constants are slightly misnamed because K_SELECT was
already taken for a different purpose.
