Main issue : there is no way to format the input when it is updated with 'val()' function.
Calling 'resetPattern' is the good solution, unfortunally the input get focus; this cause troubles on IE7 (inputs are blinking continuously) and on modern browsers since focus are stolen.
So I disabled the caret manipulation on 'resetPattern'

+1 to this. Did not expect resetPattern to steal focus.

Much appreciated on yet another PR :D Would love to see a test implemented to confirm the fix and avoid and future regression.
