havepatch: new script to easily check if a mailed patch is applied Right now this only works on the hg repo, and it assumes the patch was applied as a descendant of 3.5 to keep the checks quick. In a perfect world I'd be able to do this all with obsolete marker checks, but that doesn't seem to be a good option yet.
