instead of git-sequencer; if you're not interested, you can stop

You can do this without having to manually go to the right patch with
the -p <patchname> flag to stg refresh. In my experimental branch,
this even works together with path limited refresh, or refresh of just
the index.

My own workflow is different: I generally make a large number of
rather small "work-in-progress" commits without much of a commit
message, and every now and then (while I still have everything in
short-term memory) I use "stg coalesce" to make one or more "real"
patches out of them. Because I've committed such small pieces in the
first place, I rarely need to split a patch.

The best way I've found of splitting a patch in StGit is to open the
diff in an Emacs buffer, then pop the patch, and then use Emacs' cool
diff-mode features to apply hunks selectively, split hunks, edit files
in place, etc., and committing at the points where I want patch
boundaries. Occasionally, I'll push and pop the patch to get a new
diff with only the remaining stuff.

I imagine something like this could work without StGit as well, since
it's mostly Emacs doing all the hard work. (And I suppose there are
other tools besides Emacs that can do this?)
