Although it won't solve the non-wrapping of overly long URLs, try the
attached patch to make links clickable.  Naming the anchor shouldn't be
a major overhaul.

Good reasons exist for this functionality to have been removed from RT2
to RT3.  Please be aware that this can be a security issue (XSS).

The regexp is based on http://www.foad.org/~abigail/Perl/url2.html

Cheers,
