Ah, OK.

Yes, you can use setup_revisions() command line parsing, intercept
the result of parsing before prepare_revilimit_list() reduces that
to a contiguous set of commits that are reachable from some of the
positive refs and are not reachable from any of the negative ones,
so it certainly is doable.
