A bit more verbose still: Document the negative form on its own line
with a generated description -- requires no new syntax:

     -v, --invert-match         show non-matching lines
     --no-invert-match          opposite of --invert-match, default
     -I, --no-index             find in contents not managed by git
     --index                    opposite of --no-index, default

I would expect _("opposite of %s, default") is acceptable by l10n
folks, and assuming it is, the above would be a good approach.

The ", default" part is not correct in all cases, though, in particular
when the default depends on the output being a terminal, or arguably
when it's dependent on a config setting.  We better drop it from the
generated message.

I was seeing what is likely to be in the -rc1 that will happen in
next week, and noticed that this discussion is left unconcluded.  I
am tempted to declare that the latest iteration that shows the
negation of "--no-foo" as "--[no-]no-foo" is "good enough" for now,
and leave the above improvement as one potential future direction.

While it could certainly be improved in the future I think
"--[no-]no-foo" is probably good enough. I definitely prefer it over
"--[[no-]no]-foo"

Generating help lines for the opposite variant of all negatable options
feels quite spammy.  It almost doubles the length of the short help
because we have so many of them.  Doing that only for --no-... options
is much more compatc because most options are positive:

    -v, --[no-]invert-match    show non-matching lines
    -I, --no-index             find in contents not managed by git
    --index                    opposite of --no-index

Objections?  Otherwise the 5-patch series will be in 'next'.

Patch 5 has a trivial merge conflict in t/t0040-parse-options.sh due to
448abbba63 (short help: allow multi-line opthelp, 2023-07-18), which is
easily resolved by adding --longhelp, and a silent automatic mismerge of
t/t1502/optionspec.help due to c512643e67 (short help: allow a gap
smaller than USAGE_GAP, 2023-07-18), which requires removing three line
newlines.

How about dropping patch 5 for now?  We don't need to rush this pretty
intrusive change of output.  And the first four patches are worthwhile
in their own right, I think.
