* hitting control-c (causing SIGINTR) would cause the SIGINTR handler to

be called.  it'd cleanup() then exit().  however, cleanup() is scheduled
  to run at exit via atexit().  This means that it gets run twice, and
  this causes confusion for things like endwin().  The end result is
  that rather than actually exiting and printing the "sysinst terminated"
  message, after one control-c it looks like it's still sitting at the
  last screen you were viewing even though it's actually at a shell prompt.
  squelch the cleanup() in the SIGINTR handler to avoid this problem.
* while here, nuke the annoying space before the "sysinst terminated."
  message.  it looks bad, and serves no purpose.
