The way to reconcile these would be to customize it, I think. For example
have a string variable that contains the punctuation characters to be
included at the end. Or a regexp.

By the way, thing-at-point-url-path-regexp also disallows : inside a url.
These would be necessary to accept IPv6 IP addresses.
