This commit changes *.h files to default to C (instead of C++), and
deprecates the existing `g:c_syntax_for_h` and `g:ch_syntax_for_h`
variables in favor of a unified `g:filetype_h`, like is used for other
ambiguous file extensions.

Problem: completion: not possible to limit number of matches
Solution: allow to limit the matches for 'complete' sources by using the
"{flag}^{limit}" notation (Girish Palya)
This change extends the 'complete' option to support limiting the
number of matches returned from individual completion sources.
**Rationale:** In large files, certain sources (such as the current
buffer) can generate an overwhelming number of matches, which may cause
more relevant results from other sources (e.g., LSP or tags) to be
pushed out of view. By specifying per-source match limits, the
completion menu remains balanced and diverse, improving visibility and
relevance of suggestions.
A caret (`^`) followed by a number can be appended to a source flag to
specify the maximum number of matches for that source. For example:
```
:set complete=.^9,w,u,t^5
```
In this configuration:
- The current buffer (`.`) will return up to 9 matches.
- The tag completion (`t`) will return up to 5 matches.
- Other sources (`w`, `u`) are not limited.
This feature is fully backward-compatible and does not affect behavior
when the `^count` suffix is not used.
The caret (`^`) was chosen as the delimiter because it is least likely
to appear in file names.

Problem: During insert-mode completion, the most relevant match is often
the one closest to the cursor—frequently just above the current line.
However, both `<C-N>` and `<C-P>` tend to rank candidates from the
current buffer that appear above the cursor near the bottom of the
completion menu, rather than near the top. This ordering can feel
unintuitive, especially when `noselect` is active, as it doesn't
prioritize the most contextually relevant suggestions.
Solution: This change introduces a new sub-option value "nearest" for the
'completeopt' setting. When enabled, matches from the current buffer
are prioritized based on their proximity to the cursor position,
improving the relevance of suggestions during completion
(Girish Palya).
Key Details:
- Option: "nearest" added to 'completeopt'
- Applies to: Matches from the current buffer only
- Effect: Sorts completion candidates by their distance from the cursor
- Interaction with other options:
- Has no effect if the `fuzzy` option is also present
This feature is helpful especially when working within large buffers where
multiple similar matches may exist at different locations.
You can test this feature with auto-completion using the snippet below. Try it
in a large file like `vim/src/insexpand.c`, where you'll encounter many
potential matches. You'll notice that the popup menu now typically surfaces the
most relevant matches—those closest to the cursor—at the top. Sorting by
spatial proximity (i.e., contextual relevance) often produces more useful
matches than sorting purely by lexical distance ("fuzzy").
Another way to sort matches is by recency, using an LRU (Least Recently Used)
cache—essentially ranking candidates based on how recently they were used.
However, this is often overkill in practice, as spatial proximity (as provided
by the "nearest" option) is usually sufficient to surface the most relevant
matches.
```vim
set cot=menuone,popup,noselect,nearest inf
def SkipTextChangedIEvent(): string
# Suppress next event caused by <c-e> (or <c-n> when no matches found)
set eventignore+=TextChangedI
timer_start(1, (_) => {
set eventignore-=TextChangedI
})
return ''
enddef
autocmd TextChangedI * InsComplete()
def InsComplete()
if getcharstr(1) == '' && getline('.')->strpart(0, col('.') - 1) =~ '\k$'
SkipTextChangedIEvent()
feedkeys("\<c-n>", "n")
endif

Problem: completion: cannot configure completion functions with
'complete'
Solution: add support for setting completion functions using the f and o
flag for 'complete' (Girish Palya)
This change adds two new values to the `'complete'` (`'cpt'`) option:
- `f` – invokes the function specified by the `'completefunc'` option
- `f{func}` – invokes a specific function `{func}` (can be a string or `Funcref`)
These new flags extend keyword completion behavior (e.g., via `<C-N>` /
`<C-P>`) by allowing function-based sources to participate in standard keyword
completion.
**Key behaviors:**
- Multiple `f{func}` values can be specified, and all will be called in order.
- Functions should follow the interface defined in `:help complete-functions`.
- When using `f{func}`, escaping is required for spaces (with `\`) and commas
(with `\\`) in `Funcref` names.
- If a function sets `'refresh'` to `'always'`, it will be re-invoked on every
change to the input text. Otherwise, Vim will attempt to reuse and filter
existing matches as the input changes, which matches the default behavior of
other completion sources.
- Matches are inserted at the keyword boundary for consistency with other completion methods.
- If finding matches is time-consuming, `complete_check()` can be used to
maintain responsiveness.
- Completion matches are gathered in the sequence defined by the `'cpt'`
option, preserving source priority.
This feature increases flexibility of standard completion mechanism and may
reduce the need for external completion plugins for many users.
**Examples:**
Complete matches from [LSP](https://github.com/yegappan/lsp) client. Notice the use of `refresh: always` and `function()`.
```vim
set cpt+=ffunction("g:LspCompletor"\\,\ [5]). # maxitems = 5
def! g:LspCompletor(maxitems: number, findstart: number, base: string): any
if findstart == 1
return g:LspOmniFunc(findstart, base)
endif
return {words: g:LspOmniFunc(findstart, base)->slice(0, maxitems), refresh: 'always'}
enddef
autocmd VimEnter * g:LspOptionsSet({ autoComplete: false, omniComplete: true })
```
Complete matches from `:iabbrev`.
```vim
set cpt+=fAbbrevCompletor
def! g:AbbrevCompletor(findstart: number, base: string): any
if findstart > 0
var prefix = getline('.')->strpart(0, col('.') - 1)->matchstr('\S\+$')
if prefix->empty()
return -2
endif
return col('.') - prefix->len() - 1
endif
var lines = execute('ia', 'silent!')
if lines =~? gettext('No abbreviation found')
return v:none # Suppresses warning message
endif
var items = []
for line in lines->split("\n")
var m = line->matchlist('\v^i\s+\zs(\S+)\s+(.*)$')
if m->len() > 2 && m[1]->stridx(base) == 0
items->add({ word: m[1], info: m[2], dup: 1 })
endif
endfor
return items->empty() ? v:none :
items->sort((v1, v2) => v1.word < v2.word ? -1 : v1.word ==# v2.word ? 0 : 1)
enddef
```
**Auto-completion:**
Vim's standard completion frequently checks for user input while searching for
new matches. It is responsive irrespective of file size. This makes it
well-suited for smooth auto-completion. You can try with above examples:
```vim
set cot=menuone,popup,noselect inf
autocmd TextChangedI * InsComplete()
def InsComplete()
if getcharstr(1) == '' && getline('.')->strpart(0, col('.') - 1) =~ '\k$'
SkipTextChangedIEvent()
feedkeys("\<c-n>", "n")
endif
enddef
inoremap <silent> <c-e> <c-r>=<SID>SkipTextChangedIEvent()<cr><c-e>
def SkipTextChangedIEvent(): string
# Suppress next event caused by <c-e> (or <c-n> when no matches found)
set eventignore+=TextChangedI
timer_start(1, (_) => {
set eventignore-=TextChangedI
})
return ''
enddef
```

Problem:
- Help tags provide a good way to navigate the Vim documentation, but
many help documents don't use them effectively. I think one of the
reasons is that help writers have to look up help tags manually with
`:help` command, which is not very convenient.
- 'iskeyword' is only set for help buffers opened by `:help` command.
That means if I'm editing a help file, I cannot jump to tag in same
file using `Ctrl-]` unless I manually set it, which is annoying.
Solution:
- Add omni completion for Vim help tags.
- Set 'iskeyword' for `ft-help`
