We do want to keep some extra options back because __gitcomp_builtin
cannot show all supported options of format-patch. The reason is a
subset of options is handled by setup_revisions() which does not have
--git-completion-helper support.

I have no comment about this. In an ideal world, sendemail.perl could
be taught to support --git-completion-helper but I don't think my
little remaining Perl knowledge (or time) is enough to do it. Perhaps
this will do. I don't know.
