Problem: When 'wildmode' is set to include "noselect", the popup menu (pum)
incorrectly retained its scroll position when reopened. This
meant that after scrolling down through the menu with `<C-n>`,
reopening the menu (e.g., by retyping the command and
triggering completion again) would show the menu starting from
the previously scrolled position, rather than from the top.
This could confuse users, as the first visible item would not
be the first actual match in the list.
Solution: Ensure that the popup menu resets its scroll position to the
top when reopened (Girish Palya).

Problem: Messages routed to the pager to be shown in full, enter the
pager automatically, yielding another "press-q-prompt".
Solution: Only enter the pager when requested explicitly. Otherwise,
close the pager on the next typed mapping, unless that mapping
entered the pager.
Problem: vim._extui unconditionally creates windows, buffers and the
Vimscript cmdline highlighter when it is first loaded.
Solution: Schedule first creation of the window so that first redraw
happens sooner (still need to create at least the cmdline
window asap as it can have a different highlight through
hl-MsgArea; thus further delaying until the first event that
needs a particular target seems redundant). Load the cmdline
highlighter on the first cmdline_show event.
Problem: When a floating window with high winblend uses a highlight group
with underline (but without guisp), the underline appears red.
Solution: Only blend the special color (for underline/undercurl) if the
foreground highlight actually has underline or undercurl set.
Otherwise, ignore the special color.
Problem: ext_messages cannot tell when the screen was cleared, which is
needed to clear visible messages. An empty message is also
never emitted, but clears messages from the message grid.
Solution: Repurpose the "msg_clear" event to be emitted when the screen
was cleared. Emit an empty message with the `empty` kind to
hint to a UI to clear the cmdline area.
Problem: ext_messages is implemented to mimic the message grid
implementation w.r.t. scrolling messages, clearing scrolled
messages, hit-enter-prompts and replacing a previous message.
Meanwhile, an ext_messages UI may not be implemented in a way
where these events are wanted. Moreover, correctness of these
events even assuming a "scrolled message" implementation
depends on fragile "currently visible messages" global state,
which already isn't correct after a previous message was
supposed to have been overwritten (because that should not only
happen when `msg_scroll == false`).
Solution: - No longer attempt to keep track of the currently visible
messages: remove the `msg_ext(_history)_visible` variables.
UIs may remove messages pre-emptively (timer based), or never
show messages that don't fit a certain area in the first place.
- No longer emit the `msg(_history)_clear` events to clear
"scrolled" messages. This opens up the `msg_clear` event to
be emitted when messages should actually be cleared (e.g.
when the screen is cleared). May also be useful to emit before
the first message in an event loop cycle as a hint to the UI
that it is a new batch of messages (vim._extui currently
schedules an event to determine that).
- Set `replace_last` explicitly at the few callsites that want
this to be set to true to replace an incomplete status message.
- Don't store a "keep" message to be re-emitted.
Problem: "cmdline_show" event may be emitted with an invalid cursor
position, causing a redraw that will clear the match highlight.
Solution: Mark the cursor position as valid so that a "cmdline_show"
callback that updates the screen does not clear the match highlight.
Problem: OptionSet autocmd emitted with invalid grids after entering
tabpage with different 'cmdheight'.
Solution: First call `tabpage_check_windows()` before changing 'cmdheight'.
Add a test that exercises the `vim._extui` cmdline.
Problem: UI buffers may be 'unmodifiable' and use a 'swapfile'.
Solution: Set the 'modifiable' and 'noswapfile' options.

Problem: No ext_messages kind for the :command, :version commands.
:version is emitted as multiple events.
Solution: Assign them the "list_cmd" kind. Use `msg_put*` to properly
format the message as a single event.
Problem: The "append" parameter added in abb40ece is missing from
history entries, resulting in different message formatting
for "g<".
Solution: Add "append" field to message history entries.

Problem: Uninitialized grid for a "win" relative float when redrawing
just after it has been opened.
Solution: Ensure window grid is allocated or assigned the default grid.
Add '^' and '$' around the pattern. This makes it less likely to make
mistakes of when writing tests with {MATCH:}, as most such tests have
text before and after {MATCH:}.
Problem: Since 48e2a736, prompt messages are handled by an actual
active cmdline, resulting in `State` no longer being equal
to `MODE_CONFIRM` which is used in some places. E.g. to
specify the current `mode()` or to re-emit a confirm message.
Solution: Replace `MODE_CONFIRM` with a new `MODE_CMDLINE` sub-mode when
`ccline.one_key/mouse_used` is set. Use it to avoid clearing
mouse_used prompt messages, and to re-emit one_key messages
(when ext_messages is inactive, for which this is unnecessary).
Problem: When using 'winblend', transparent backgrounds (-1) are forced
to default colors (usually black) during attribute blending, breaking
the transparency effect.
Solution: Check original background colors before blending in
hl_blend_attrs(). If both background and foreground originally had
transparent backgrounds, preserve transparency instead of forcing
default colors.
Problem: `exists()` checks should test for being equal to 1 rather than truthy, and extui check can be more restrictive.
Solution: Adjust `exists()` guards to equal 1 and use `matchparen#CursorMoved`.
Problem: Last diff folds not merged (after v8.1.1922)
Solution: loop over all windows in the current tabpage and update all
folds (Gary Johnson)
This commit fixes a bug where the last two folds of a diff are not
merged when the last difference between the two diff'd buffers is
resolved.
Normally, when two buffers are diff'd, folding is used to show only the
text that differs and to hide the text that is the same between the two
buffers. When a difference is resolved by making a block of text the
same in both buffers, the folds are updated to merge that block with the
folds above and below it into one closed fold.
That updating of the folds did not occur when the block of text was the
last diff block in the buffers.
The bug was introduced by this patch on August 24, 2019:
patch 8.1.1922: in diff mode global operations can be very slow
Problem: In diff mode global operations can be very slow.
Solution: Do not call diff_redraw() many times, call it once when
redrawing. And also don't update folds multiple times.
Unfortunately, folds were then not updated often enough.
The problem was fixed by adding a short loop to the ex_diffgetput()
function in diff.c to update all the folds in the current tab when the
last difference is removed.
A test for this was added to test_diffmode.vim. Two of the reference
screen dumps for another test in that file,
Test_diffget_diffput_linematch(), had to be changed to have all the
folds closed rather than to have the last diff block remain open.

Problem: "msg_history_show" event is emitted when `msg_silent > 0`.
E.g. when capturing its output with `execute()`, which also
doesn't work with ext_messages.
Solution: Don't emit the "msg_history_show" event when `msg_silent > 0`.
Call regular messaging functions when `redirecting()`, to
execute `redir_write()` while ensuring the message itself
is not emitted.
fix(api): ensure win_get_config() is reciprocal
Problem: win_get_config() does not include a 'none' border field,
causing nvim_open_win() to apply the 'winborder' value.
Solution: Include a 'none' border field in the returned config,
such that it can be used reciprocally in nvim_open_win()
to yield the same window layout.
Problem: "win" is cleared in float config after 96330843, even with
unchanged "relative".
Solution: Don't clear "win". Avoid erroring for deleted "win" by setting
the parent win to curwin directly when "win" is zero or not
present in config.
Problem: Unable to change the "relative" of a flag after its target
"win" no longer exists.
Solution: Unset target window if it is not present in config and
reconfigured "relative" no longer expects a target window.
Problem: Non-visible/focusable windows are assigned a window number,
whereas commands that use this window number skip over them.
Solution: Skip over non-visible/focusable windows when computing
the window number, unless it is made the current window
through the API in which case an identifiable window number
is still useful. This also ensures it matches the window
number of the window entered by `<winnr>wincmd w` since
403fcacf.
Problem: Blockwise Visual selection not redrawn correctly when moving
cursor for more than 1 cells with 'virtualedit'.
Solution: Restore the curswant update removed in 6679687bb3.
Problem: Unable to emit a message with arbitrary kind.
Solution: Add a "kind" opts field to nvim_echo().
Use it to set the "list_cmd" kind for vim.show_pos().
Problem: Search highlighting is applied strangely to the filler text of
transparent folds, and EOL list characters are not shown.
Solution: Don't apply search highlighting to the last column of the window row
if the last text char on the line is highlighted. Display the EOL list char if
needed. Don't highlight the entire filler text when matching EOL, just highlight
the EOL list char or the first filler char.
Problem: "99 searchcount ought to be enough for anyone."
Solution: Increase `SEARCH_STAT_DEF_MAX_COUNT` to 999, which I'm sure
will suffice for the next twenty years.

Problem: Consecutive "msg_show" events stemming from an `:echon`
command are supposed to be appended without a newline, this
information is not encoded in the "msg_show" event.
Solution: Add an "append" parameter to the "msg_show" event that is set
to true to indicate the message should not start on a new line.
Considered alternative: Emit a newline for the common case instead at the
start of a new message. That way UIs can more closely follow the logic
as it is implemented for the message grid currently. This would be a
breaking change. The "append" parameter seems OK.
Problem: When scrolling (the text) down with 'smoothscroll', filler
lines are revealed before the text skipped with `w_skipcol`.
Solution: Check `w_skipcol` before filler lines.
Problem: If the only highlight present in the buffer is an extmark, and its end
position is outside the screen, redraws that start on lines after the
first line of the mark will consider the buffer as not having any highlights,
and skip drawing the mark's highlight.
Solution: Check the updated number of decor ranges.
Problem: Extui does not route messages emitted as a result of a typed
command to the "more" window.
Command message leading shell messages is missing a kind.
Messages not routed to 'cmdheight' area after it was 0.
Solution: Route messages that were emitted in the same event loop as an
entered command to the "more" window. Also append multiple
messages in an already open more-window.
Assign it the `shell_cmd` kind.
Change message position when 'cmdheight' changes from 0.
Problem: Messages that are already added to the history are not emitted
as part of the "g<" msg_history_show event.
Solution: Move clearing the history for temporary messages to before
adding a message to the history, rather than after emitting
a message.
