url: remove \t \n \r in url.parse() similar to WHATWG
Browse files Browse the repository at this point in the history
WHATWG URL removes tab, new line, and carraige return characters before
processing URL strings. To narrow the differences between WHATWG URL and
url.parse(), and thus reduce opportunities for host spoofing etc. due to
differences between the two APIs, let's do the same with url.parse().
