This aligns its behaviour better with `nvim_win_close`.
Note that `:hide` is actually incapable of closing the cmdwin, unlike `:close`
and `:quit`, so this is a bit of a difference in behaviour.
Disallow closing the previous window from `nvim_win_close`, as this will cause
issues.
Again, no telling how safe this is. It also requires exposing old_curwin. :/
Also note that it's possible for the `&cmdheight` to change if, for example,
there are 2 tabpages and `nvim_win_close` is used to close the last window in
the other tabpage while `&stal` is 1. This is addressed in a later commit.
Problem: As discussed on Matrix, there was some interest in having
`nvim_open_win` again be able to open floats in the cmdwin (e.g: displaying a
hover doc related to what's in the cmdwin). After #23228, this was disallowed.
Solution: Allow `nvim_open_win` in the cmdwin as long as `!enter` and
`buffer != curbuf` (the former can cause all sorts of issues, and the latter
can crash Nvim after closing cmdwin). Also allow `nvim_win_set_buf` in a similar
fashion.
Note that we're not *entirely* sure if this is 100% safe (cmdwin is a
global-state-using-main-loop-calling beast), but this seems to work OK..?
Also:
- Check the buffer argument of `nvim_open_win` earlier, and abort if it's
invalid (it used to still open a window in this case).
- Untranslate `e_cmdwin` errors in the API (other errors in the API are not
translated: although not detailed in the API contract yet, errors are
supposed to be stable).
When signature is a bit long or there are too many tags, the tags appear
before the signature's line. Don't include the line with tags in the
previous function' docs.
Also fix lint warnings.
Problem: The evalfunc.c file is too big.
Solution: Move undo functions to undo.c. Move cmdline functions to
ex_getln.c. Move some container functions to list.c.

Undo functions only. Cmdline functions have already been moved.
A lot of container functions have been added to eval/funcs.c instead of
list.c in previously ported Vim 8.2.x patches, so deal with that later.

Problem:
The cmdpreview saved undo nodes on cmdpreview_prepare() from ex_getln.c may
become invalid (free) if the preview function makes undo operations, causing
heap-use-after-free errors.
Solution:
Save the buffer undo list on cmdpreview_prepare)_ and start a new empty one. On
cmdpreview_restore_state(), undo all the entries in the new undo list and
restore the original one. With this approach, the preview function will be
allowed to undo only its own changes.

Problem: No test for bad use of spaces in help files.
Solution: Add checks for use of spaces in help files. Ignore intentional
spaces. (Hirohito Higashi, closesvim/vim#11952)

Problem:
Content that has codeblocks with different languages, results in
multiple calls to:
syntax include vim syntax/vim.vim
which raises error:
E403: syntax sync: line continuations pattern specified twice
Before ba8f19ebb6, this was avoided by
using pcall() to ignore the error.
Solution:
Restore the use of pcall() to ignore the error.
We plan to replace this logic with a treesitter approach, so this is
good enough for now.
Fix#24431
* fix(lsp): replace @private with @nodoc for public client functions
To prevent lua-ls warnings in plugins which use the functions.
* fix(lsp): remove duplicate type annotations/class definitions
These annotations became duplicate with https://github.com/neovim/neovim/pull/23750
When adding `workspace/didChangeWorkspaceFolders` support to my [language server](https://github.com/elixir-tools/next-ls), I noticed that when neovim removes a workspace, it sends an empty table (which is serialized to an empty JSON array) for the value in the `added` field.
This does not follow the spec; the `added` table should just be empty.
The following error led me to this discovery. Note the payload includes `"added" => [[]]`:
```

In the case you hit this warning in a buffer (like with C++ and clangd),
this message potentially fires over and over again making it difficult
to use the editor at all.
Problem:
netrw may conflict with the Nvim default "gx" mapping.
Solution:
Initialize keymapping earlier by moving it to vim._init_default_mappings().
That also avoids needing to check maparg().
Problem: Cannot drag a vertical separator to the right of a window
whose 'statuscolumn' is wider than itself.
Solution: Never treat a click on a vertical separator as a click on
'statuscolumn'.
Problem:
When the CurSearch highlight group is set, and a search is active and
you are listening to the remote UI "win_viewport" events, then typing is
very unresponsive, because "win_viewport" is not sent as soon as the
character is typed. On the other hand if you refresh the screen on
"flush", the screen will scroll with a delay since "win_viewport" comes
too late. I estimate this delay be up to one second, but it varies.
Solution:
Call validate_cursor() before drawing the screen, just like other modes.
No tests have been added because only the intermediate state is wrong.
Avoid consecutive RPC requests involving :startinsert or :stopinsert,
because consecutive RPC requests may be processed together, before the
:startinsert or :stopinsert takes effect.
Also change some feed_command() to command() to make tests faster.
Problem:
On Windows, `rundll32` exits zero (success) even when given
a non-existent file.
Solution:
Mock vim.system() on Windows to force a "failure" case.
Previously, when using foldmethod=indent, inserting an unindented line
would inadvertently open closed folds below it.
As a performance improvement, folds were only updated once, across all
lines, after Insert mode was exited.
Now, the performance improvement is no longer being used when
foldmethod=indent, so folds are updated multiple times during Insert
mode, but only across the lines that are changing, which preserves the
folds (and their open/close states) instead of recreating them.
