I didn't know about url-truncate-url-for-viewing, no other reason.

I'd be happy with your change, but note that it will always truncate
URLs that are wider than the current frame - there is no way to have no
truncation take place.

If a user is most familiar with something like ffap to open URLs then
this is unfortunate - ffap doesn't see the full URL in the buffer.
