Hi,
A request came up on the FreeBSD-questions list earlier for the
-maxdepth option as found in GNU find to work in FreeBSD's find. It
turns out that -prune will do what this guy wanted, but would it be a
good idea to add -maxdepth (and -mindepth just to be consistent) for
any other people who might want it? I've attached a patch to implement
this, if I don't get any feedback I'll send-pr it instead, I thought I
might get a few opinions here first.
