We used to try loose objects first with sha1_object_info(), but packed objects first with read_sha1_file(). Now, prefer packed objects over loose ones with sha1_object_info(), too.
Usually the old behaviour would pose no problem, but when you tried to fix a fscked up repository by inserting a known-good pack,
git cat-file $(git cat-file -t <sha1>) <sha1>
could fail, even when
git cat-file blob <sha1>
would _not_ fail. Worse, a repack would fail, too.
