There are pure fixes and this "-title" enhancement intermixed.
Can we have fixes-only first?

Is a fix.

Is a fix.  How could we have missed this?

Is an enhancement -- I suspect it is not worth to switch
depending on the length of $comment_long.  Does it clutter the
output too much if you did -title to everybody?

Is an enhancement.  I think the matching hunk to fix the same
"$cgi->a() output concatenated as print argument" problem is
missing here.  And the next hunk the same comment as the one for
git_summary applies.

And as you say, git_summary and git_tags do look similar.  Maybe
we would want to refactor them first to clean things up before
piling up more features?
