Yes, ok (almost).  Can you just change the ``if'' to use the:

	if test ...
	then
	    ..
	fi

rather than

	if test ...; then
	    ..
	fi

so that it is consistent with the rest of the file (unless you can find 
a GNU SH SCRIPT coding standard which indicates otherwize :-).

I'm also trying to remember if TR has any portability issues (not your 
problem but your patch reminded me :-)
