[PATCH] git-fsck: report missing author/commit line in a commit as an error

[Martin Koegler <mkoegler@auto.tuwien.ac.at>]

Report a commit date (returned by parse_commit), if it is zero
as an error (instead by a printf).

A zero date means missing author/commiter line or a totally
corrupted commiter line.
