max_len poorly worded

[rwitchell]

I feel the max_len needs to be re-written in the master version.
For example, a postcode is 4 digits, max_len,4
The output is: The postcode field needs to be shorter than 4 characters.
Which is incorrect, it needs to be 4 or less characters.

Either, the wording needs to change to "field needs to be $param or shorter in length"
or you need to increase the $param by one, as shown below.

case 'validate_max_len':
    $param++;
    if($param == 1) {
        $resp[] = "The <span class=\"$field_class\">$field</span> field needs to be shorter than $param character";
    } else {
        $resp[] = "The <span class=\"$field_class\">$field</span> field needs to be shorter than $param characters";
    }
    break;
case 'validate_min_len':
    $param--;
    if($param == 1) {
        $resp[] = "The <span class=\"$field_class\">$field</span> field needs to be longer than $param character";
    } else {
        $resp[] = "The <span class=\"$field_class\">$field</span> field needs to be longer than $param characters";
    }
    break;

I've updated this in the master branch, thanks for pointing it out!
