Problem:
Continue separators normalization, and try to keep it at the
nvim <-> external boundary, e.g., `fn.xxx`, `api.xxx`, `:xxx`
Solution:
some key changes
- normalize `$HOME-windows`
- normalize entry points of changing directory
- `nvim_set_current_dir()`, `chdir()`
- normalize the named pipe
- `--listen` arg, `--server` arg, `:restart`
- `serverstart()`, `sockconnect()`, `serverstop()`
- make `expand()` respect 'shellslash' again
- clean up `did_set_shellslash`
- replace `forward_slash` with `TO_SLASH`
- remove obsolete `TMP_PATHSEPSTR`
- remove `slash_adjust` in `do_autocmd_dirchanged`?
- make `fnamemodify()` always return `/` (except when substituting
separators via `:s`, `:gs` ?)
Note:
- these funcs still apply `slash_adjust` on return, as before:
`:pwd`, `chdir()`, `exepath()`, `getcwd()`
- these funcs alwarys return `/`, unlike before the normalization PRs
- `getcompletion()`, `finddir()`, `findfile()`
Also
- clean up code, comments, formatting and tests
- move `TO_SLASH` from `f_chdir` to `changedir_func`
- move `TO_SLASH` from `f_bufadd` to `buflist_new`

Problem: [security]: s:NetrwLocalRmFile() escapes only the backslash in
the file name before passing it to :execute, so a name
containing "|" injects arbitrary Ex commands when the file is
deleted (cipher-creator)
Solution: Use fnameescape() to correctly escape the file name
(Yasuhiro Matsumoto).

Problem: unmarking a regular file when there are directories in the markings
list also removes the 2match highlight from those directories.
Solution: correctly rebuild the match pattern from the remaining markings,
using the right regex trailer for each entry in the list.

Problem:
* 'shellcmdflag' states that its default value is set according to the
value of 'shell', but this behavior is not yet implemented on Windows.
The same applies to 'shellpipe', 'shellredir', and 'shellxquote'.
* On Windows, Git is often installed in paths containing spaces, and we
still do not correctly resolve the sh executable name as described in
'shell'.
* On Windows, the default value of 'shellslash' is always `false`,
which causes Unix-like shells to interpret `\` in paths returned by
some functions as escape charaters.
Solution:
Use a simple rule table to detect common shells (e.g. `cmd`,
`powershell`, shells whose names contain `csh` or `sh`) and apply
best-effort defaults, while leaving more complex scenarios to user
configuration.
Problem: To goto or delete a bookmark, one needs to prefix a count
for the bookmark number (e.g., "2gb" to open bookmark#2).
As the bookmark list gets or deletes entries, the numbers
keep changing, requiring listing the bookmarks with qb to
discover the desired bookmark number. Typing gb or mB
without a count targets g:netrw_bookmarklist[-1].
Solution: If no count is given to gb or mB, list all bookmarks and
prompt for a number using inputlist(), similar to tag jump
with g].

Problem: the bookmarks list can have duplicate entries, more often
in win32 (due to mixed slashes and capitalization) and when
g:netrw_keepdir=0 (which could introduce relative paths).
Duplicate entries could be: C:\foo\BAR\baz.file
c:\foo\bar\baz.file
c:/foo\BAR/baz.file
BAR/baz.file
Solution: Normalize the paths and make sure they are always absolute
(J. Paulo Seibt).

Problem: off-by-one bug in s:NetrwUnMarkFile()
Solution: Correctly loop through all buffers to unlet all variables
(J. Paulo Seibt)
When the function loops through buffers to clear s:netrwmarkfilelist_#
and s:netrwmarkfilemtch_#, it skips the last one at bufnr('$'), messing
up mark highlights and causing other functions that operate on those
arrays (like delete or rename) to target stale marked files.
The bufnr() help page says that bufnr("$") returns the highest buffer
number of existing buffers, so while ibuf < bufnr("$") does not clear
the last buffer-local arrays.
To reproduce:
Just opening a fresh Vim and running :Ex opens a netrw buffer at the
highest number. Then, typing mu after marking some files triggers the
mark highlight bug, and finally typing D would act like calling the
delete function against the previous marked files, as the buffer-local
arrays where not touched by s:NetrwUnMarkFile.

Problem: runtime(netrw): ~ note expanded on MS Windows
(Tom Vamvanij)
Solution: Expand ~ on MS Windows (Yasuhiro Matsumoto)
On Windows, ":Explore ~" did nothing because the tilde expansion was
gated to Unix/Cygwin only. Additionally, substitute() interprets
backslashes in the replacement string specially (e.g. \U as a case
modifier), which would corrupt $HOME values like C:\Users\name even
if the branch were taken.
Include has("win32") in the guard, anchor the pattern to the start of
the string, and escape backslashes, ampersands and tildes in $HOME
before substituting.

Problem: tests: Test_netrw_FileUrlEdit.. fails on Windows
(after 3e60f03d942d6bb0f7)
Solution: Skip the test on Windows (Yasuhiro Matsumoto).
The Test_netrw_FileUrlEdit_pipe_injection() test fails on Windows with
E303 because '|' is not a valid filename character on Windows. Since
the pipe character cannot appear in a Windows filename, the command
injection vector this test guards against does not apply on Windows.
