Subject: [PATCH] Differentiate between a minCharacters of 0 and undefined.

The comment at line 65 implies that setting minCharacters to 0 will result in no matches being displayed when there are no characters in the search box (e.g. if you've backspaced your search term). The code was treating 'undefined' and 0 identically.
