No, you're right. I misread the code as:
file_size(...) < 0
rather than what it really says:
file_size(...) < 1
Sorry for the noise.
That it was so easy to misread the code, however, may be a good
argument for making a more special-purpose function, such as
file_empty_or_missing() (or file_not_empty()) as suggested in the
patch 3/4 thread.
