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.
Problem: Computing fold levels for an empty buffer (somehow) breaks the
parser state, resulting in a broken highlighter and foldexpr.
Cached foldexpr parser is invalid after filetype has changed.
Solution: Avoid computing fold levels for empty buffer.
Clear cached foldinfos upon `FileType`.
Problem: after #32458, it may still be possible for `busy_start` UI events to be
emitted without matching `busy_stop`s in the terminal.
Solution: do `terminal_enter`'s cursor visibility check immediately after
setting/restoring State so it occurs before events. This ensures that if pending
escape sequences are processed while in `terminal_enter`, the cursor's initial
visibility is set before `is_focused` is checked by `term_settermprop`.
As a result, we can move the call to `showmode` back to where it was originally.
Problem: Edit test is flaky when run under valgrind.
Solution: Send some text to the terminal to trigger a redraw.

Problem: This keyword is used by GCC and Clang to prevent -Wpedantic
(and other options) from emitting warnings for many GNU C extensions.
This is used heavily in Alpine Linux through musl libc and
foritfy-headers. Without filtering the __extension__ keyword some type
definitions are duplicated. For example, timeval is defined once as
struct timeval { time_t tv_sec; suseconds_t tv_usec; };
and once as:
__extension__ struct timeval { time_t tv_sec; suseconds_t tv_usec; };
Without this patch, the LuaJIT C parser doesn't recognize that these
definitions are equivalent, causing unit test to fail on Alpine Linux.
Solution: Filter out the keyword in filter_complex_blocks.
Problem: `showmode` in `terminal_enter` may cause `vpeekc` to process events,
which may handle pending escape sequences. If `CSI ? 25 l` is handled to hide
the cursor, it may remain hidden even after leaving terminal mode if both
`terminal_enter` and (indirectly) `showmode` call `ui_busy_start`, as there is
only one matching call to `ui_busy_stop` after leaving terminal mode.
Solution: let `terminal_enter` handle setting the initial visibility of the
cursor before calling `showmode`.
Closes#32456.
This simple solution assumes it isn't possible for e.g. `os_breakcheck` to be
called indirectly by something else before `terminal_enter` initially handles
cursor visibility and after it restores it, which I think is true.
`command` was already resolved via a `completionItem/resolve` request
but only if `additionalTextEdits` were also present, and the
`resolveSupport` capability wasn't listed.

Problem: autotrigger option of vim.lsp.completion.enable() would trigger
all clients, as long as it matched at least one client's
triggerCharacters.
Solution: trigger only the clients with triggerCharacters matching the
character. overtriggering still happens if any client returns
isIncomplete=true (this case is more involved).

vim-patch:partial:9.1.1084: Unable to persistently ignore events in a window and its buffers
Problem: Unable to persistently ignore events in a window and its buffers.
Solution: Add 'eventignorewin' option to ignore events in a window and buffer
(Luuk van Baal)
Add the window-local 'eventignorewin' option that is analogous to
'eventignore', but applies to a certain window and its buffers. Identify
events that should be allowed in 'eventignorewin', adapt "auto_event"
and "event_tab" to encode this information. Window context is not passed
onto apply_autocmds_group(), and when to ignore an event is a bit
ambiguous when "buf" is not "curbuf", rather than a large refactor, only
ignore an event when all windows into "buf" are ignoring the event.

Problem: The behavior of the visual search mappings aren't consistent
with their normal mode counterparts.
- The count isn't considered
- Searching with an empty selection will match every character in the
buffer
- Searching backwards only jumps back when the cursor is positioned at
the start of the selection.
Solution:
- Issue `n` `v:count1` times
- Error out and exit visual mode when the selection is empty
- Detect when the cursor is not at the start of the selection, and
adjust the count accordingly
Also, use the search register instead of the more error-prone approach
of feeding the entire search string as an expression
Problem:
`vim.tbl_get(tbl, nil, 1)` returns `tbl` itself. In this case, `keys` is not
empty, but `ipairs` skips the iteration:
local keys = { nil, 1 }
assert(#keys == 2)
for i, k in ipairs(keys) do
assert(false, 'unreachable')
end
Solution:
Use `select("#", ...)` and `select(i, ...)` to ensure consistency for count and
iteration.

Problem: setreg() doesn't correctly handle mbyte chars in blockwise

Solution: use mb_ptr2len_len function pointer (Yee Cheng Chin)
setreg() will automatically calculate the width when a blockwise mode is

characters when value is passed as newline-terminated string. It does
work when value is passed as a list of lines though.
Fix this by properly using the mbyte function pointer to increment the
loop counter.

Problem: filetype: Mill files are not recognized
Solution: detect '*.mill' files as scala filetype
(author)
In the past [Mill](https://mill-build.org/mill/index.html) build files
were always `build.sc` and treated as Scala files. However as the 0.12.x
series of mill you can create a `build.mill` file. You can see a lot of
examples of this if you search
[GitHub](https://github.com/search?q=build.mill&type=code). This small
change just ensures that if you have a `*.mill` file it treats it as a
Scala file.
