I actually think this is a bit too broad.  The calling process of
this program does know that it is feeding list of raw object names
(prefixed with ^ for negative ones), but the codepath this patch
touches does not know who is calling it with what.  It would be
safer to introduce a mechanism for the caller to tell this codepath
not to bother checking refnames, as it knows it is feeding the raw
object names and not refnames.

After all, you can feed things like "refs/heads/master" from the
standard input of "git pack-objects --revs", no?
