[issue38789] difflib lacks a way to check if results are empty

[Simon Friedberger]

Hi Tim!

Sorry, if my explanation wasn't clear.

For some of the iterators - like the one produced by ndiff - the iterator will always return data, even if there is no difference in the files.

My current solution is to run difflib.unified_diff and check if the iterator is non-empty and then run difflib.ndiff again to get the output that I want.
