Fix -mindepth and -maxdepth to not drill down into excluded directories.

The fact other implementations don't implement "! -mindepth" doesn't mean we can't. Also, find uses +N, N, -N for everything else but this extension doesn't. Also, -depth already had a definition and this has nothing to do with that. It's a poorly thought-out extension, is what I'm saying.
