Problem: With $d='[dir]', `:e $d/file.txt` opens the wrong file,
`:e $d/<Tab>` fails to complete, and `glob('$d/*')` returns
nothing. Wildcard characters inside expanded environment
variables get picked up by globbing again.
Solution: Turn the 4th parameter of expand_env_esc() from a bool into a
string of characters to escape in each expanded value. Callers
that pass the result to wildcard expansion should include
PATH_ESC_WILDCARDS in addition to " \t" (glepnir).

Problem: Wrong cursor position when entering command line window
Solution: Add check_cursor() command to verify the cursor position

line. Add check_cursor() after setting State to MODE_NORMAL so the
cursor is adjusted to the last character.
Also fix the cmdwin prefix character (e.g. ':') being drawn on wrapped
continuation rows. Draw an empty space instead so that the text
alignment is preserved.

Problem: Cmdline history not updated when mapping both <Up> and <CR>.
Solution: Consider the command typed when in Cmdline mode and there is
no pending input (zeertzjq).
Although the existing behavior technically does match documentation, the
"completely come from mappings" part is a bit ambiguous, because one may
argue that the command doesn't completely come from mappings as long as
the user has typed a key in Cmdline mode. I'm not entirely sure if this
change will cause problems, but it seems unlikely.

Problem: When the popup menu (PUM) occupies more than half the screen
height, it flickers whenever a character is typed or erased.
This happens because the PUM is cleared and the screen is
redrawn before a new PUM is rendered. The extra redraw between
menu updates causes visible flicker.
Solution: A complete, non-hacky fix would require removing the
CmdlineChanged event from the loop and letting autocompletion
manage the process end-to-end. This is because screen redraws
after any cmdline change are necessary for other features to
work.
This change modifies wildtrigger() so that the next typed
character defers the screen update instead of redrawing
immediately. This removes the intermediate redraw, eliminating
flicker and making cmdline autocompletion feel smooth
(Girish Palya).
Trade-offs:
This behavior change in wildtrigger() is tailored specifically for
:h cmdline-autocompletion. wildtrigger() now has no general-purpose use
outside this scenario.

Problem:
insert-mode ctrl-r input is treated like raw user input, which is almost
never useful. This means any newlines in the input are affected by
autoindent, etc., which is:
- slow
- usually breaks the formatting of the input
Solution:
- ctrl-r should be treated like a paste, not user-input.
- does not affect `<c-r>=`, so `<c-r>=@x` can still be used to get the
old behavior.

Problem: fuzzy-matching can be improved
Solution: Implement a better fuzzy matching algorithm
(Girish Palya)
Replace fuzzy matching algorithm with improved fzy-based implementation
The
[current](https://www.forrestthewoods.com/blog/reverse_engineering_sublime_texts_fuzzy_match/)
fuzzy matching algorithm has several accuracy issues:
* It struggles with CamelCase
* It fails to prioritize matches at the beginning of strings, often
ranking middle matches higher.
After evaluating alternatives (see my comments
[here](https://github.com/vim/vim/issues/17531#issuecomment-3112046897)
and
[here](https://github.com/vim/vim/issues/17531#issuecomment-3121593900)),
I chose to adopt the [fzy](https://github.com/jhawthorn/fzy) algorithm,
which:
* Resolves the aforementioned issues.
* Performs better.
Implementation details
This version is based on the original fzy
[algorithm](https://github.com/jhawthorn/fzy/blob/master/src/match.c),
with one key enhancement: **multibyte character support**.
* The original implementation supports only ASCII.
* This patch replaces ascii lookup tables with function calls, making it
compatible with multibyte character sets.
* Core logic (`match_row()` and `match_positions()`) remains faithful to
the original, but now operates on codepoints rather than single-byte
characters.
Performance
Tested against a dataset of **90,000 Linux kernel filenames**. Results
(in milliseconds) show a **\~2x performance improvement** over the
current fuzzy matching algorithm.

Problem: The :keep{alt,jumps,marks,patterns} commmands are sometimes
misidentified as :k.
Solution: Make sure one_letter_cmd() only returns true for :k and not
other :keep* commands (Doug Kearns).
This currently manifests as missing completion for :keep* commands and
incorrect results from fullcommand().
E.g., fullcommand("keepmarks") returns "k" rather than "keepmarks".
The correct command, however, is executed as command modifiers are
handled specially in do_one_cmd() rather than using find_ex_command().
Fix exists(':k') so that it returns 2 for a full match.

Problem: cannot easily trigger wildcard expansion
Solution: Introduce wildtrigger() function
(Girish Palya)
This PR introduces a new `wildtrigger()` function.
See `:h wildtrigger()`
`wildtrigger()` behaves like pressing the `wildchar,` but provides a
more refined and controlled completion experience:
- Suppresses beeps when no matches are found.
- Avoids displaying irrelevant completions (like full command lists)
when the prefix is insufficient or doesn't match.
- Skips completion if the typeahead buffer has pending input or if a
wildmenu is already active.
- Does not print "..." before completion.
This is an improvement on the `feedkeys()` based autocompletion script
given in vim/vim#16759.

Problem: completion: search completion match may differ in case
(techntools)
Solution: add "exacttext" to 'wildoptions' value (Girish Palya)
This flag does the following:
exacttext
When this flag is present, search pattern completion
(e.g., in |/|, |?|, |:s|, |:g|, |:v|, and |:vim|)
shows exact buffer text as menu items, without
preserving regex artifacts like position
anchors (e.g., |/\<|). This provides more intuitive
menu items that match the actual buffer text. However,
searches may be less accurate since the pattern is not
preserved exactly.
By default, Vim preserves the typed pattern (with
anchors) and appends the matched word. This preserves
search correctness, especially when using regular
expressions or with 'smartcase' enabled. However, the
case of the appended matched word may not exactly
match the case of the word in the buffer.

Problem: When using `/` or `?` in command-line mode with 'ignorecase' and
'smartcase' enabled, the completion menu could show items that
don't actually match any text in the buffer due to case mismatches
Solution: Instead of validating menu items only against the user-typed
pattern, the new logic also checks whether the completed item
matches actual buffer content. If needed, it retries the match
using a lowercased version of the candidate, respecting
smartcase semantics.

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).
