— forked from gruber/Liberal Regex Pattern for Web URLs
Updated @gruber's regex with a modified version that looks for 2-13 letters rather than trying to look for specific TLDs, and many other improvements. (UPDATE 2018-07-30: Support for IPv4 addresses, bare hostnames, naked domains, xn-- internationalized domains, and more... see comments for BREAKING CHANGE.)
