That worked great, thanks!  In case it's useful to anyone else, here's what I did in addition to the above:

-- current
macFactory.addStep( steps.Git( repourl=repoURL, branch="master", mode="incremental", alwaysUseLatest=False ) )

-- new
macFactory.addStep( steps.Git( repourl=repoURL, branch="master", mode=Property('source_mode'), alwaysUseLatest=False ) )

And then add the property to each scheduler with something like:

-- current
schedulers.append(  SingleBranchScheduler( name="master", branch="master", ... )

-- new
schedulers.append(  SingleBranchScheduler( name="master", branch="master", properties={'source_mode': 'incremental'}, ... )

I'd like to configure the Force scheduler to override the "mode" property of the source step so I can force a clean build but I can't figure out how to do it from the docs at https://docs.buildbot.net/0.8.14/developer/cls-forcesched.html?highlight=force <https://docs.buildbot.net/0.8.14/developer/cls-forcesched.html?highlight=force>.
