rev-list --objects: fix object list without commit.

Junio C Hamano · Junio C Hamano · commit ef1cc2cc216b · 2005-12-19T16:19:06.000-08:00
Earlier, "rev-list --objects &lt;sha1&gt;" for an object chain that
does not have any commit failed with a usage message.  This
fixes "send-pack remote $tag" where tag points at a non-commit
(e.g. a blob).
