Sorry for the delay, but such huge patches really are tough to review
in detail (and I'd advise to proceed with separate patches for separate
issues).

Please! Usually patches have to go to mainline first, and only then to
a release branch.

I fixed the ChangeLog entry as follows and committed the part of your
patch which is included below.
2003-04-23 James A Morrison <ja2morri at uwaterloo dot ca>
* invoke.texi: Eliminate extra white-space caused by @gccoptlist{
on its own line.
Ensure there are two spaces between each pair of options and add
@gol where appropriate.
Note that your original submission has an error in the Darwin part
(a duplicate option, but I have the print out at work) and contained
one or two changes you didn't mention.
Also, for new stuff, how about having one command-line option per line
of texi source? (This applies to the part where you introduced a new
@gccoptlist.)
Thanks for this cleanup! If you have any further changes to mainline
and/or the 3.3-branch, please send the mainline variant first, ideally
acompanied by a patch for the branch that applies on top of the mainline
patch (ignoring any rejects I might get when applying the former on the
branch).
(In case you wonder, this avoid quite a bit of duplicate review work. ;-) )
Thanks,
Gerald
