[Buildbot-devel] Git command fails only via force build

[Dan Savilonis]

Do you mean the master.cfg? This is just a buildbot.steps.source.Git buildstep.

I noticed that there seem to be a different sequence of git commands
done in previous (successful) builds, so I'm not sure yet that this
particular command line sequence ever worked.
