I am debating myself if it is sane for this option to have no hint
that it is about limiting in its name. --author/--committer
don't and it is clear from the context of the command that they are
not about setting author/committer, so --reflog-message may be
interpreted the same, perhaps.
The entry in the context above talks about multiple occurrence of
that option. Shouldn't this new one also say what happens when it is
given twice?

Please add comment to ensure that FIELD_MAX stays at the end; if you
ensure that, the result is much better than the original we know
committer is at the end so add one.
I think I wrote prep_header_patterns() and compile_grep_patterns()
carefully enough not to assume the headers are only the author and
committer names, so the various combinations i.e. all-match,
author(s), committer(s), grep(s), and reflog-message(s), should work
out of the box, but have you actually tested them?
I do not know offhand the matching side is prepared to take random
garbage fields. IIRC, we strip the trailing timestamp from committer
and author header lines when we match, and a new code needs to be
added to control when that stripping should / should not kick in
depending on the header.

This part looks familiar and smells sane ;-)
