Re: [PATCH 09/18] fsck: handle multiple authors in commits specially

This problem has been detected in the wild, and is the primary reason
to introduce an option to demote certain fsck errors to warnings. Let's
offer to ignore this particular problem specifically.

If we have an option to demote this to a warning, wouldn't we want
to do the same fsck_ident() on that secondary author line?

 	if (!skip_prefix(buffer, "committer ", &buffer))
 		return report(options, &commit->object, FSCK_MSG_MISSING_COMMITTER, "invalid format - expected 'committer' line");
 	err = fsck_ident(&buffer, &commit->object, options);
