undo-tree.el provides undo tree functionality. Vim provides undo tree
functionality. Vimpulse emulates Vim.

I actually like Emacs' undo better, i.e. I like the current behaviour
better than Vim's more extensive undo steps -- it's trivial to hit `u'
twice instead of once, whereas it's non-trivial (impossible AFAIK) to
only undo a part of an undo step. I personally would just get rid of the
currently defunct vimpulse-connect-undos code entirely. 

OTOH, Vimpulse emulates Vim, so you can argue it should restore the
bigger undo steps.
