autocomplete and minChars = 0

autocomplete and minChars = 0

I wanted to have the following behaviour:
- Set the minChars of an autocompleter to 0
- When the focus is set to this field, it should automatically get its
autocomplete results from the specified URL.

Apparently, I needed a hack to get this working:

               if (options.minChars == 0 && !$input.val()) {
                       request('', receiveData, hideResultsNow)
               }
               else {
                       $.each(trimWords($input.val())
, function(i, value) {
                               request(value, findValueCallback, findValueCallback);
                       });
               }

(the $.each() with the subsequent request() are on line 186..188 of the original autocomplete 1.1 non-minified version)

Did I do something wrong with my arguments, or is this a case that was not working in the first place?
