I assumed that in such a case, where the contributor is (or we are) making several commits to fix mistakes in a submission, we would use a "squash merge" (?) to combine all the changes in the pull request into a single commit on master. The GitHub web interface provides an option for this. If we want to rebase instead of merge (?) we would need to write up a procedure for how that's accomplished.
