Files changed on a specific branch

[Mark Brown]

I am interested in generating a report of all files that have changed since
a certain date or since a tag was created, but would like to limit the
report to only those files changed on a specific branch.  How would such a
report be generated?  I can generate a report of all files changed on all
branches, but how to only show files on one branch?  Thank you for your
help.
