Keywords and options recently got dedicated highlighting roles in
b3626d48e (Highlight keywords differently, 2021-02-04) and
711796ad1 (Highlight options differently, 2021-10-19)
but still default to "command" and "parameter", respectively.
The dedicated roles were not colored by our CSS theme,
which makes a "test -f foo.txt" look weird:
- "test" is dark blue (since it's a command)
- "foo.txt" is light blue (since it's a parameter)
- "-f" is black (weird!)
The CSS theme doesn't support configuration, so the dedicated
highlighting roles should always default to their fallback
options. Make it so.
This corrects what looks like wrong alignment of some synopsis lines.
(I think the alignment is not a bad idea but it makes us do more
manual work, maybe we can automate that in future. We still need to
figure out how to translate it to HTML.)
"man -l build/user_doc/man/man1/history.1" before:
string match [-a | --all] [-e | --entire] [-i | --ignore-case]
[-r | --regex] [-n | --index] [-q | --quiet] [-v | --invert]
PATTERN [STRING…]
and after:
string match [-a | --all] [-e | --entire] [-i | --ignore-case]
[-r | --regex] [-n | --index] [-q | --quiet] [-v | --invert]
PATTERN [STRING…]
Also make the lines align the same way in the RST source by carefully
choosing the position of the backslash. I'm not sure why we used
two backslashes per line. Use only one; this gives us no choice
of where to put it so both source and man page output are aligned.
Change tabs to spaces to make the alignment in the source work.
The ellipsis is a grammar metacharacter, just like the []()|.
Write *FOO*… instead of *FOO…*, so the ellipsis is not underlined
in the man page. Not super sure about this one.
This matches the style in man(1) (except that we use the … ligature).
A previous iteration did the reverse (never use a space before the
ellipsis). That would be a smaller change.
We use plural "*OPTIONS*" more often than "*OPTION*...", so let's do
that everywhere.
In some other places where we do have an ellipsis, make sure to use
singular, since the ellipsis already means repetition. This change
is incomplete, and I'm not sure if this is worth it, since it's
subjective, so I might drop it.
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.

Unfortunately the normal font families like "sans-serif" and
"monospace" are basically broken because the browser defaults are
decades old.
TODO: Inline code is barely distinguishable.
Unfortunately this removes the index also from the sidebar in other pages. This makes it basically inaccessible.
Maybe there is a way to not show it in the list at the bottom, but this isn't it. Maybe a manual list of pages instead of reusing the TOC?
This reverts commit b5a95317f0.
