I think the current message is more accurate as it implies both:
	1. There is no file, and
	2. If there is, it is not empty

"unexpectedly empty" may imply that there is a directory which is not empty
and that is not the intention of the function.

I think we should relocate the function `test_must_be_empty` in a separate
patch as this patch deals with a different issue.
