parse: Ignore -- on the command line.
find uses -- to indicate the end of the flags. That is, $ find -L -- -type f is allowed, but $ find -- -L -type f results in an error about an unknown predicate `-L`. This behaviour doesn't seem particularly useful -- in particular, unlike most other tools, it doesn't help you if you want to specify a filename beginning with a -. So to ensure bfs is compatible with all GNU find command lines, we just ignore -- whenever it appears.
