   Here's another problematic URL:


   thingatpt ignores the final `;'.


According to RFC3986 (aka STD066), this is wrong; ";" is legitimate
anywhere in a path or query part, including the end.  So are "." and
",", but thing-at-point-url-path-regexp also refuses to match these
characters at the end of the string.  Doing (ffap-string-at-point 'url)
drops these characters plus ":", "!", and (questionably) "?".

   It may not be possible to find a tradeoff between RFC compliance and
parsing dwimmery that would satisfy everybody.  Since stripping off
trailing punctuation is useful behavior (ISTR it's worked this way for a
while now), I would recommend against changing it now.  However, a case
could be made for making thing-at-point and ffap-string-at-point
consistent.  Perhaps "!:;.," would be best?  This is just the union of
the two sets but without the dubious inclusion of "?".
