Helm seems to treat "!" specially in pattern matching, so having a ! in the pattern string when traversing directories is problematic. This change fixes #2737, because as far as I can tell "+" has no special meaning in a helm pattern. Of course, we can choose a different character, but I'm fond of "+" as representing "more layers here".
