Problem: cmdline-completion for comma-separated options wrong
Solution: Fix command-line expansions for options with filenames with
commas
Fix command-line expansions for options with filenames with commas
Cmdline expansion for option values that take a comma-separated list
of file names is currently not handling file names with commas as the
commas are not escaped. For such options, the commas in file names need
to be escaped (to differentiate from a comma that delimit the list
items). The escaped comma is unescaped in `copy_option_part()` during
option parsing.
Fix as follows:
- Cmdline completion for option values with comma-separated file/folder
names will not start a new match when seeing `\\,` and will instead
consider it as one value.
- File/folder regex matching will strip the `\\` when seeing `\\,` to
make sure it can match the correct files/folders.
- The expanded value will escape `,` with `\\,`, similar to how spaces
are escaped to make sure the option value is correct on the cmdline.
This fix also takes into account the fact that Win32 Vim handles file
name escaping differently. Typing '\,' for a file name results in it
being handled literally but in other platforms '\,' is interpreted as a
simple ',' and commas need to be escaped using '\\,' instead.
Also, make sure this new logic only applies to comma-separated options
like 'path'. Non-list options like 'set makeprg=<Tab>' and regular ex
commands like `:edit <Tab>` do not require escaping and will continue to
work.
Also fix up documentation to be clearer. The original docs are slightly
misleading in how it discusses triple slashes for 'tags'.

Problem: The style guide currently recommends having a `default:` case for switch statements that are not conditional on an enumerated value. Additionally, it recommends using `assert(false)` if `default:` is unreachable. This is problematic because `assert()` only runs on debug builds, which may lead to confusing breakages in release builds. Moreover, this suggestion is followed nowhere in the C code and `abort()` is used everywhere instead.
Solution: Suggest using `abort()` instead of `assert(false)`, that way the program always terminates if a logically unreachable case is reached.

Problem:
On Windows, "gf" fails on a filepath that has a line:column suffix.
Example:
E447: Can't find file "src/app/core/services/identity/identity.service.ts:64:23"
Solution:
- Remove ":" from 'isfname' on Windows. Colon is not a valid filename
character (except for the drive-letter).
- Handle drive letters specially in file_name_in_line().
Fixes#25160
Problem:
The swapfile "E325: ATTENTION" dialog is displayed when editing a file
already open in another (running) Nvim. Usually this behavior is
annoying and irrelevant:
- "Recover" and the other options ("Open readonly", "Quit", "Abort") are
almost never wanted.
- swapfiles are less relevant for "multi-Nvim" since 'autoread' is
enabled by default.
- Even less relevant if user enables 'autowrite'.
Solution:
Define a default SwapExists handler which does the following:
1. If the swapfile is owned by a running Nvim process, automatically
chooses "(E)dit anyway" (caveat: this creates a new, extra swapfile,
which is mostly harmless and ignored except by `:recover` or `nvim -r`.
2. Shows a 1-line "ignoring swapfile..." message.
3. Users can disable the default SwapExists handler via `autocmd! nvim_swapfile`.
Problem: win32: missing '**' expansion test (after v9.0.1947)
Solution: Add test for MS-Windows
win32: Add "**" test
Vim supports "**" on MS-Windows. However, it is not tested by
`Test_glob_extended_bash`.
Unlike Unix, it doesn't use 'shell' and doesn't support {,} expansion.
So, I added as a separate test.

Problem: cannot complete option values
Solution: Add completion functions for several options
Add cmdline tab-completion for setting string options
Add tab-completion for setting string options on the cmdline using
`:set=` (along with `:set+=` and `:set-=`).
The existing tab completion for setting options currently only works
when nothing is typed yet, and it only fills in with the existing value,
e.g. when the user does `:set diffopt=<Tab>` it will be completed to
`set diffopt=internal,filler,closeoff` and nothing else. This isn't too
useful as a user usually wants auto-complete to suggest all the possible
values, such as 'iblank', or 'algorithm:patience'.
For set= and set+=, this adds a new optional callback function for each
option that can be invoked when doing completion. This allows for each
option to have control over how completion works. For example, in
'diffopt', it will suggest the default enumeration, but if `algorithm:`
is selected, it will further suggest different algorithm types like
'meyers' and 'patience'. When using set=, the existing option value will
be filled in as the first choice to preserve the existing behavior. When
using set+= this won't happen as it doesn't make sense.
For flag list options (e.g. 'mouse' and 'guioptions'), completion will
take into account existing typed values (and in the case of set+=, the
existing option value) to make sure it doesn't suggest duplicates.
For set-=, there is a new `ExpandSettingSubtract` function which will
handle flag list and comma-separated options smartly, by only suggesting
values that currently exist in the option.
Note that Vim has some existing code that adds special handling for
'filetype', 'syntax', and misc dir options like 'backupdir'. This change
preserves them as they already work, instead of converting to the new
callback API for each option.

Problem: No support for writing extended attributes
Solution: Add extended attribute support for linux
It's been a long standing issue, that if you write a file with extended
attributes and backupcopy is set to no, the file will loose the extended
attributes.
So this patch adds support for retrieving the extended attributes and
copying it to the new file. It currently only works on linux, mainly
because I don't know the different APIs for other systems (BSD, MacOSX and
Solaris). On linux, this should be supported since Kernel 2.4 or
something, so this should be pretty safe to use now.
Enable the extended attribute support with normal builds.
I also added it explicitly to the :version output as well as make it
able to check using `:echo has("xattr")`, to have users easily check
that this is available.
In contrast to the similar support for SELINUX and SMACK support (which
also internally uses extended attributes), I have made this a FEAT_XATTR
define, instead of the similar HAVE_XATTR.
Add a test and change CI to include relevant packages so that CI can
test that extended attributes are correctly written.

Use `tic -x` instead of `tic` to include any unknown capabilities in a modern `terminfo.src` as user-defined ones, instead of dropping them. Modern ncurses behavior with `tic -x` will not change.

Problem: filename expansion using ** in bash may fail
Solution: Try to enable the globstar setting
Starting with bash 4.0 it supports extended globbing using the globstar
shell option. This makes matching recursively below a certain directory
using the ** pattern work as expected nowadays. However, we need to
explicitly enable this using the 'shopt -s globstar' bash command.
So let's check the bash environment variable $BASH_VERSINFO (which is
supported since bash 3.0 and conditionally enable the globstar option,
if the major version is at least 4. For older bashs, this at least
shouldn't cause errors (unless one is using really ancient bash 2.X or
something).

Recommend adding a space after i.e. `--- @see`.
The "space" variant is common for the vast majority of docstring formats
such as doxygen, javadoc and typescript.
Problem:
NVIM_APPNAME does not allow path separators in the name, so relative
paths can't be used:
NVIM_APPNAME="neovim-configs/first-config" nvim
NVIM_APPNAME="neovim-configs/second-config" nvim
Solution:
Let NVIM_APPNAME be a relative path. Absolute paths are not supported.
fix#23056fix#24966
A lot of updated places in the docs were already incorrect since long
since they did not reflect the default behaviour.
"[dos format]" could've been argued being better for discoverability
but that ship has already sailed as it is no longer displayed by default.
The "f" flag was removed in f7da472257.
The value of the "f" flag is no longer listed in the 'shortmess'
description and it cannot be disabled, so having it in the default value
is pointless and confusing.
Oldtests clean up after themselves, and the options that need operators
to align with Vim all deny duplicates, so there is no need to set them
to default.
Also make the variable name that test_listchars.vim uses to align with
Vim more obvious.
Not everything needs to be crazy overconfigurable.
Also fixes a warning in latest clang which didn't approve of
the funky math switch statement in append_arg_number
- Remove the usage of the term "defer" to avoid confusion with
`vim.defer_fn`, which also calls `vim.schedule_wrap` internally.
- Explicitly state that `vim.schedule_wrap` returns a function in the
text.
- Mention that arguments are passed along.
- Include a usage example.
- Rename param to `fn`.
