Based on experimentation, csh's test is something like:

	if I can read from the file and the first character is not #
		give it to sh
	else
		give it to csh

Thus a zero-length file, as a degenerate case, is run by the csh.
The only difference between csh and sh for a zero-length file is,
of course, that .cshrc is sourced.
