I noticed this buglet when working on the PR80828 fix:
The introductory paragraph to the Option Index appendix says: "GCC’s
command line options are indexed here without any initial ‘-’ or ‘--’."
Indeed, that was mostly true, but there were ~20 index entries that
incorrectly included the leading dash. Fixed thusly.

* doc/invoke.texi: Remove leading dash from @opindex entries
throughout the file.
