I know there's been some discussion about opening URLs from e-mails in Sup, and
because many people use Sup via an SSH session, client-side solutions are not
universally useful... but here is a patch that seems to copy a URL on the
currently highlighted line to the X selection buffer. (From there I use Kupfer
http://kaizer.se/wiki/kupfer/ to open the link in a web client.)
Obviously you can do something similar with a mouse but I use a
netbook and try to avoid using the trackpad if I can.

It relies on having the program xsel available in your path.

I've never fiddled in Ruby before so accept my apologies if the lines are
ridiculous, and also if this has been done before by others.

For the reasons I mention (not universal, requires xsel) I don't
expect it to make it into the Sup code base but I put it out here in
case it suits anyone else.
