`#!' is supposed to be *simple*. . . !

No, because `#!' can create at most one argument, so this would
pass the string "-c \"sed -d $1 | tbl | nroff -ms | lpr\"" (in C
notation) to /bin/sh.  What will work is this:

	#! /bin/sh
	tbl << '*end*of*text*' | nroff -ms | lpr
	.PP
	Hello.
	...
	*end*of*text*
