Title: diffpatch support

I've added two things:

* the help lines in the __Gundo__ buffer didn't list all the keys one could use. I added more (but not all) of those.
* I added a 'd' keymapping that will do a 'vert diffpatch' of the current undo level against the current file (useful for exploring differences between the current undo and some other arbitrary change).
