- click-and-drag doesn't work for X11 mouse report overriding

- it'd be nice to have the scrollbar move when the arrows are pressed
  and to scroll continuously.

- speed-up screen refreshes

- add X11 mouse highlighting mode? (NOT LIKELY)

- fix problem with pixel-droppings left when bold has been simulated
  using an overstrike. (NOT LIKELY)

- a better resizing mechanism that avoids truncating lines and also
  unwraps autowrapped lines?  Why bother, xterm doesn't.

- add support for spawning modules (like the way fvwm does).
  It should then be possible to make a standalone Tek or other graphics
  window and even some simple pop-up mouse menus that could communicate
  with rxvt, but not bloat its size.  Nice idea, but I'll never have time
  to even start, so eager volunteers would be nice.

- catch SIGURG?  The Unixware rlogin problem.

- utmp support still not working? - should be better now.

- scrollbar bug - inconsistent refresh of the scrollbar shadows on Linux,
  but seems okay on AIX (for instance) ... perhaps the X server settings?

- fix configure to detect SVR4 and to handle install properly when it is
  found to be ./install.sh
