> Since MNG-7080 introduced this option we mimic grep's behavior, but not the way grep actually does.
> GNU grep: https://git.savannah.gnu.org/cgit/grep.git/tree/src/grep.c#n2751
> FreeBSD grep: https://github.com/freebsd/freebsd-src/blob/781c3b51193e5bd99773439192ca68fdfdd9c330/usr.bin/grep/grep.c#L576-L596
> * Both make the value for {{--color}} optional and default to {{auto}}
> * They also accept {{tty}}, {{if-tty}}, {{yes}}, {{force}}, {{none}}, {{no}}
> We should support that approach too: Optional value and privately accepting additional values.
