What is the motivation for checking that the size is not zero? Zero is
like any other size too small to contain the target directory contents,
so I don't see why we would add a specific check for it.

Your commit log unfortunately only explains *what* the commit is doing
(which is obvious by reading the code) but not *why* this change is
necessary.

Thanks!

Thomas
