The git-webkit pr --overwrite doesn't handle modifying the file listing between runs so one has to keep track of it manually before the actual commit. Can this be moved to be something the commit queue handles?
Not sure if we have another bug for this, but this has been discussed. I think that yes, the message should be updated on every amend commit, intelligently preserving what is still relevant from the previous version.
