This feels way too specialized to live as part of parse_options
infrastructure.
The existing caller(s) may want to use this callback for parsing
"points-at" option they have, but is that the only plausible use of
this callback? It looks to be usable by any future caller that
wants to take and accumulate any object names into an sha1-array, so
perhaps rename it to be a bit more generic to represent its nature
better?
parse_opt_object_name()
or something?
I also wonder if we can (and want to) refactor the users of
with-commit callback. Have them use this to obtain an sha1-array
and then convert what they received into a commit-list themselves.
