doc: List more valid -x option arguments
Commit Message
Hi!
We miss quite a few -x option arguments that can be specified.
Ok for trunk?
2026-01-09 Jakub Jelinek <jakub@redhat.com>
* doc/invoke.texi (-x): Add c++-system-module, objc-cpp-output,
objc++-cpp-output, adascil, adawhy, modula-2, modula-2-cpp-output,
rust, algol68 and lto as further possible option arguments.

This is fine in terms of content, but I have some nit-picky concerns
about formatting.

It would be good to consistently use two spaces between items in this
list, but I am afraid this line may end up being too long and overflow
the right margin in the PDF output. Can you either check that it
doesn't, or split it into two shorter lines?

Likewise consistently use two spaces on this line too.
