Err, this will segv when it fails; better to use

	lb = a + strlen("\nauthor ");
	lb = strchrnul(lb, '<');
	rb = strchrnul(lb, '>');
	eol = strchrnul(rb, '\n');
	if (!*lb || !*rb || !*eol)
		die("invalid commit: %s", use_message);

This is even more permissive, but I think that’s okay.

Sorry for the noise.
Jonathan
