On our 3b2, 3b5, and 3b15 AT&T systems running SYSV.2 and SYSV.3, sh does
something rather unfortunate when certain built-in functions fail.  For
example,

	cd nowhere || echo 'cd failure'

where ``nowhere'' is nonexistent does not (as you might expect) cause ``cd
failure'' to be echoed to the screen.  The expected error message is produced
and then . . . nothing, a new prompt.

This became a problem for us when a cron script which checked for the existence
of a directory in this (admittedly crude) fashion started breaking.  The
script chokes and dies whenever the cd fails.  It seems to happen with other
built-in functions as well; for instance, the ``.'' function does the same
thing when the file given it does not exist.

Luckily, ``test'' works just fine, so we can run around this problem.

BTW, ksh handles all this stuff correctly.

Does anyone have a fix?
