The v7 /bin/sh doesn't give any 'no match' errors; it merely passes
the original string along.  But a more serious problem is redirection
and pipe characters, which are acted on before the program can see
anything.  I'm constantly cursing out the shell when I try

	grep ^foobar xyz

and I'm told 'foobar: not found'.
