Comment (by int-e):

 Replying to [comment:1 duncan]:
 > I get this behavior with runghc too. It adds some control character to
 the end of the output. This makes it unusable in many scripting
 applications and breaks some testsuite tests. Again, setting TERM=vt100 or
 similar rather than "xterm" fixes it.

 Good point. I tried that with my patch and it fixes that case as well,
 even when input is from a terminal.
