Although not incorrect, the double-negative is hard to digest. I had
to read it a few times to convince myself that it matched the intent
of the new function. I wonder if a message such as

    echo "'$1' is unexpectedly empty"

would be better. (Subjective, and not at all worth a re-roll.)

Much later in this same file, a function named test_must_be_empty() is
defined, which is the complement of your new test_file_not_empty()
function. The dissimilar names may cause confusion, so choosing a name
more like the existing function might be warranted.

Also, it might be a good idea to add this new function as a neighbor
of test_must_be_empty() rather than defining it a couple hundred lines
earlier in the file. Alternately, perhaps a preparatory patch could
move test_must_be_empty() closer to the other similar functions
(test_path_is_missing() and cousins).
