* lib/missing (sed_minuso, sed_output): New variables.
	(autom4te, help2man, makeinfo): Use them.  Unifies detection of
	`-o FILE', `--output FILE', `--output=FILE', stricter regex.
	Fixes `missing' to detect `--output' for help2man (PR 483).
	Report by Dennis J. Linse <address@hidden>.
	(autom4te): Document in `missing --help'.
	* THANKS: Update.
