Problem:
- gQ does not restore follow-mode (q=).
- Users/plugins have no way to check if follow-mode is enabled.
Solution:
Introduce buffer-local 'follow' option.
Enable EmmyLua's assign-type-mismatch diagnostic after correcting the
runtime annotations and assignments it flags.
Correct option, tuple, and return types, and use separate locals when a
value changes representation. Add guards and narrow casts where needed
so the runtime passes the stricter check. Regenerate the affected docs.

Enable EmmyLua's need-check-nil diagnostic and resolve nullable values
through more precise types, explicit invariants, and guards for missing
runtime state. Keep analyzer-specific workarounds local and update the
affected API documentation.
Exclude the bundled re.lua from analysis so its nil-check warnings do
not fail CI.

Problem:
The preview-window (:pedit, etc.) always uses a split, but it would be
useful as a floatwin (or "popup").
Solution:
Support Vim's 'previewpopup' option.
Problem:
When running nvim on a remote machine over SSH, if there is high ping,
then bg detection may not complete in time. This results in a warning
every time nvim is started. #38648
Solution:
Restore 'ttyfast' option and allow it to control whether or not bg
detection is performed. Because this is during startup and before any
user config or commands, we use the environment variable
`NVIM_NOTTYFAST` to allow disabling `ttyfast` during initialization.
Problem:
- Unable to "pin" a window to prevent closing without specifically
being targeted.
- :fclose closes hidden windows (even before visible windows).
Solution:
- Add 'winpinned' window-local option. When set, window is skipped by
:fclose and :only. Pin the ui2 cmdline window (which should always be
visible), so that it is not closed by :only/fclose.
- Skip over hidden (and pinned) windows with :fclose.

The `buffer` option remains functional but is now undocumented.
Providing both will raise an error. Since providing `buf` was disallowed
before, there is no code that will break due to using `buffer` alongside
`buf`.
Problem: completion: complete_match() Vim script function and
'isexpand' option are not that useful and confusing
(after v9.1.1341)
Solution: Remove function and option and clean up code and documentation
(Girish Palya).
complete_match() and 'isexpand' add no real functionality to Vim. They
duplicate what `strridx()` already does, yet pretend to be part of the
completion system. They have nothing to do with the completion mechanism.
* `f_complete_match()` in `insexpand.c` does not call any completion code.
It’s just a `STRNCMP()` wrapper with fluff logic.
* `'isexpand'` exists only as a proxy argument to that function.
It does nothing on its own and amounts to misuse of a new option.
The following Vim script function can be used to implement the same
functionality:
```vim
func CompleteMatch(triggers, sep=',')
let line = getline('.')->strpart(0, col('.') - 1)
let result = []
for trig in split(a:triggers, a:sep)
let idx = strridx(line, trig)
if l:idx >= 0
call add(result, [idx + 1, trig])
endif
endfor
return result
endfunc
```
