Replace "useful in this context" with "necessary in most contexts" (and,
for some contexts, use "pletoh[sl]()" rather than "pntoh[sl]()"), as per
my previous mail.

...but not if

	1) the machine on which you're running Ethereal doesn't have the
	   same byte order as the one specified for your protocol;

	2) the stuff *before* it in the packet doesn't happen to be of
	   such as size as to cause stuff to be properly aligned.
