Success, thanks!

The doStepIf function is passed step, and step.build.requests has a list
of requests (I forget the class), for each request, request.sources is a
dict of SourceStamp objects (indexed by codebase), and in each, changes
is a list of changes.

So for the first request and for a codebase called 'one', checking
whether this list is empty or not tells you whether it affects the given
codebase:

  step.build.requests[0].sources['one'].changes
