I think $(foo) is required by POSIX.

	I believe that Solaris and others (AIX IIRC) have /bin/sh linked
to /bin/ksh, and it behaves as the POSIX shell when run as /bin/ksh, but
behaves as a much more true-to-bourne shell when run as /bin/sh.

But "sh" is required to be the POSIX shell (XSH page 850.)

Thus, they might have some braindamage where /usr/bin/sh is the POSIX 
shell and /bin/sh is a braindead shell.  Sigh.
