32930	URLValidator should accept urls with port number < 10	Wu Haotian	Wu Haotian	"{{{
>>> from django.core.validators import URLValidator
>>> URLValidator()(""https://code.djangoproject.com:1"")
Traceback (most recent call last):

django.core.exceptions.ValidationError: <unprintable ValidationError object>
}}}

The commit[1] for fixing Ticket #20003 added port length checks in URLValidator, but I didn't see why in the ticket comments or commit description.

Given that:

The URL Standard from WhatWG[2] defines URL Port as: 
    A URL’s port is either null or a 16-bit unsigned integer that identifies a networking port. It is initially null. 

RFC 3986[3] defines ""port"" as ""*DIGIT"", and does not requires the length of port.

I believe URLs with port number < 10 should be valid URLs.
