But in this case the full path is in argv[0], making this the easiest
of the solutions.
	if (!argc)
		look at WBenchMsg
	else if (any {':','/'} in argv[0])
		use argv[0]
	else
		use PATH

The only case I can see that would fail is when someone gets some code
going using loadseg() explicitly, which (as far as I know, anyone want
to correct me?) does not save the executable's name anywhere.
