Postalcode validation accepts values that are longer than specified

[sldhana-zz]

I am using FormEncode postalcode validation to validate postalcodes for certain countries. For example, if I enter a postalcode of 111-111 or 111111 for Japan, it returns an error as expected. But, if I enter 111-11111 or 1111111 (any digit more than the postalcode requirements), it accepts the value. Shouldn't the length requirements of the postalcode be honored?

A PR was recently merged for this: #85 but no release has been made since.

@lambacck, any idea on the timeline? This fix is perfect for what I need to do and I am hoping to use this fix as a jumping board to add additional countries for postalcode validation.
