Zero changes is not special cased. It will still produce an
incremental, which can indeed be useful (for one thing you then know
that you have a backup as of that point in time, rather than not being
able to distinguish "no backup was taken in 5 years" from "nothing
changes in 5 years").

To be clear, the verify will compare against what's actually on the
file system. If those JPG:s in the paste below have in fact been
removed from the file system since the backup, the above would be the
expected output.
