Fix 'string length: Unknown option': add `--` before $subcommand
Fix count $subcommand always = 1 with `sudo` and `doas`:
give argv as array to __fish_complete_subcommand
[ci skip]
This mostly fixes some wrong indents or replaces some stray tab indents.
I excluded alignment on purpose, because we have a whole bunch of code
that goes like
```fish
complete -c foo -n 'some-condition' -l someoption
complete -c foo -n 'some-longer-condition' -l someotheroption
```
and changing it seems like a larger thing and would include more
thrashing.
See #3622.
This would have prevented #6323.
While we don't want to pepper `command` everywhere, `psub` is kind of
a core thing, so we should try to proof it against common problems.
CMake sets these flags to sane defaults depending on which compiler
you're using, so overriding them isn't very nice.
For example:
with g++, I get
-- Debug: -g
-- RelWithDebInfo: -O2 -g -DNDEBUG
-- MinSizeRel: -O2 -g -DNDEBUG
-- Release: -O3 -DNDEBUG
and with MSVC you get something like
-- Debug: /MDd /Zi /Ob0 /Od /RTC1
-- RelWithDebInfo: /MD /Zi /O2 /Ob1 /DNDEBUG
-- MinSizeRel: /MD /Zi /O2 /Ob1 /DNDEBUG
-- Release: /MD /O2 /Ob2 /DNDEBUG
fish will react to certain variable modifications, such as "TZ." Only do
this if the main stack is modified. This has no effect now because there
is always a single stack, but will become important when concurrent
execution is supported.
This adds string-x.rst for each subcommand x of string. The main page
(string.rst) is not changed, except that examples are shown directly after
each subcommand. The subcommand sections in string.rst are created by
textual inclusion of parts of the string-x.rst files.
Subcommand man pages can be viewed with either of:
```
man string collect
man string-collect
string collect <press F1 or Alt-h>
string collect -h
```
While `string -h ...` still prints the full help.
