read_revisions_from_stdin() has passed pointers to its read buffer down to handle_revision_arg() since its inception way back in 42cabc3 (Teach rev-list an option to read revs from the standard input., 2006-09-05). Even back then, this was a bug: through add_pending_object, the argument was recorded in the object_array's 'name' field. Fix it by making a copy whenever read_revisions_from_stdin() passes an argument down the callchain. The other caller runs handle_revision_arg() on argv[], where it would be redundant to make a copy.

So I changed my mind. Your "easy fix" looks to me the right thing to do.So here's the same with a commit message and signoff. I hope I got my history right; I didn't look too long if it had any users, but it was definitely recorded.
Thanks.
