Correct the grammar by moving the options after the command argument.
Also group the -c/--command and -p/--path pairs, to convey that the
short and long variants are equivalent.
While at it, consolidate the -C/--do-complete forms, like we usually
do.
One synopsis misrenders as
set [options] VARIABLE*[*INDICES]… VALUES…
Add a missing backslash to fix that. Also go back to uppercase
because I'm not sure why this was changed to lowercase.
Finally, remove the spurious ellipsis after VARIABLE[INDICES].
This element cannot be repeated. Multiple index values and ranges
can be specified but that's already implied by the plural INDICES.
For alteration we usually use "(a | b)", not "{a | b}".
While at it, instead of writing 4/6 subcommands in one line, write them
on separate lines, so it's very obvious that all these are separate
subcommands. We mainly use the (a | b) syntax for long/short options.
The -- is not special here and we don't mention it in other synopses.
It was originally added for a good reason in 98449fec5 (fix `math`
regression, 2017-07-14), along this addition to math.rst:
> You should always place a `--` flag separator before the expression. [...]
However, since 56d913453 (Cache math expressions, 2017-08-24) that
line was changed to
> You don't need to use `--` before the expression even if it begins with a minus sign [...]
Previously, when we got an unknown option with --ignore-unknown, we
would increment woptind but still try to read the same contents.
This means in e.g.
```
argparse -i h -- -ooo -h
```
The `-h` would also be skipped as an option, because after the first
`-o` getopt reads the other two `-o` and skips that many options.
This could be handled more extensively in wgetopt, but the simpler fix
is to just skip to the next argv entry once we have an unknown option
- there's nothing more we can do with it anyway!
Additionally, document this and clearly explain that we currently
don't transform the option.

Use the remaining_to_disclose count to determine if all completions
are shown (allows consistent behavior between short and long completion
lists).
Closes#8485
Currently,
set -q --unpath PATH
simply ignores the "--unpath" bit (and same for "--path").
This changes it, so just like exportedness you can check pathness.
Unless we use "complete --require-parameter", we must say "-w32",
not "-w 32", because the second "32" is a positional argument.
Notably, old options do not have this behavior, which is a bit weird,
see #8465

* fish_key_reader: Simplify default output
It now only prints the bind statement. Timing information and such is
relegated to a separate "verbose" mode.
* Adjust fish_key_reader docs
* Adjust tests
Unlike in other shells, for-loops do not set $status if
1. the loop count is zero, or if
2. the loop body consists of only commands like "set" that don't
set $status.
POSIX for-loops always set an exit status (they set 0 if no loop
iterations). Following that would be awkward because it would add a
lot of complexity in combination with the 2 special cases above.
Document that "for" behaves the same as "set": it will pass through
existing $status, and also the last child's $status.
See the discussion in #8409
Unfortunately, currently :program: doesn't link to the program's page.
So we use the old-school :ref: again where we should link, i.e. for
everything that's not the program the current page is about.
Fixes#8438
