Note the unbalanced ' within the ` here:

 	echo `echo 'foo`

This fails in bash and NetBSD's ksh, but not in NetBSD's sh
(and neither on Solaris' /bin/sh, /usr/xpg4/bin/sh and /bin/ksh).

Is this expected? No, I haven't checked SUSv3, but my gut feeling tells me 
our /bin/sh is not right here.

FWIW, I've discovered this while trying to build pkgsrc/lang/tcl83 on 
Linux. While I'll fix the package, I do think that our /bin/sh needs a 
whack over the head. Anybody got a cluebat? :)
