Upon further inspection, the problem is even worse.  GNU screen also
breaks selections spanning lines - it causes urxvt to treat the end of
a line as if it was fully padded with spaces.  This could actually be
a show-stopper for me using urxvt, since I rely heavily on GNU screen :-(
Ideas much appreciated!
