Comment (by 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.

 So when verifying the fix, test with runghc as well as ghc -e.
