Hmm, I dunno.  The symptom I saw was that about half of the regression
tests reported "FAIL: test-name" without any other output whatsoever.
After I switched the shell to use /bin/ksh (Korn shell) they worked.
If anyone's got an idea how to debug such failures, I'm game to look
into it ... but I'm not really sure it's worth your time.  An easy way
to override the shell selection seems like a good idea in any case,
and I'm perfectly happy if that's all you do.
