<20080216055953.d5fafe10.chriscool@tuxfamily.org>

By the way this patch also improves the existing check inside
'parse_lldiff_command' by using:
	return config_error_nonbool(var);
instead of:
	return error("%s: lacks value", var);

	This patch series can be applied on "master"
	on top of my "diff.c: strdup -> xstrdup" patch. 

	The first 3 patches apply cleanly on "next" though.
