bugzilla-tool supported it by "bugzilla-tool post-commits -b n HEAD" I have to run "git reset" for webkit-patch for now.
post-commits still works fine. webkit-patch post-commits However, "upload" doesn't support git commits yet. see: webkit-patch help --all-commands for a full list of commands.
Oh, I thought post-commits was replaced with upload. Sorry for that.
Ojan fixed this.
