Description

There are cases where a diffx diff section will have empty diff
content--for example, when a file is renamed but doesn't have any
changes to content. The diff stats generation will do the right thing if
a file is added without specifying diff= in the constructor at all,
but was spewing errors with diff=b''. This change updates things to
check for falsiness rather than explicitly checking against None.

Testing Done


Ran with some code that was creating empty (but not None) diffs. Saw no

  more errors.
Ran unit tests.

Can you add a unit test for this? I'm aiming for 100% test coverage, so tests can be used as a starting point for verifying new implementations.
