I would like to have something similar to this patch, which allows for setting the (git) tree of a particular patch. I would like to use it (from the Emacs mode) to make it easier to split an old patch into two (or more).
It might be that this is too "powerful" (read: unsafe), and maybe a better (safer) command would use whatever is currently in the index rather than a SHA1.
Anyway, I'd appreciate any comments, e.g. at http://github.com/gustavh/stgit/commits/set-tree (pull from git://github.com/gustavh/stgit.git "set-tree" branch).
