webkit-patch upload should detect local commits and suggest git reset --soft webkit-patch isn't super git-friendly. I'm not even sure that the "upload" command could be made git-friendly since it may make modifications to the ChangeLog and i'm not sure in a Git world it would make sense to auto-commit those or what? At least for the time being we should detect that the user has local commits and offer suggestions as to how to use the tool.
I don't think 'git reset --soft' is the right way to do this; I don't want to lose my local commit history until after I've landed the patch and no longer need it. I would recommend instead that we do what git-cl does, which is to create a new temporary branch, squash all of the local commits onto that branch, commit that, and then delete the temporary branch (see http://neugierig.org/software/git/?url=git-cl/tree/git-cl, lines 734 - 769 or thereabouts).
