[PATCH] Make the git-fsck-objects diagnostics more useful
Actually report what exactly is wrong with the object, instead of an ambiguous 'bad sha1 file' or such. In places where we already do, unify the format and clean the messages up. Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>
