Subject: revisions: allow --glob and friends in parse_options-enabled commands

As v1.6.0-rc2~42 (2008-07-31) explains, even pseudo-options like --not
and --glob that need to be parsed in order with revisions should be
marked handled by handle_revision_opt to avoid an error when
parse_revision_opt callers like "git shortlog" encounter them.
