Thanks for the reply Mark. After posting the question, I started looking
at the builds folders within the jobs and each build has a changelog which
has a 'tree' in it. I assume Jenkins will use that 'tree' to figure out
the changes between branches? Just guessing.
I also ran some test builds. I first ran a build on master and I got lucky
that a developer was just in the process of checking in changes to the
master. i verified that by going to the github and checking the commit
history. then, I ran a build using the same job on a child branch. The
changes were reported as zero and it confirmed with the history on git.
Then I ran another build on master again and it then the few more commits
that the developer continued making to master.
