Log message:
unf*ck undo.
No seriously. Reposition the cursor to the start of the redo
position, like emacs. This gets us halfway to being emacs-finger-friendly.
For the rest, introduce a rptcount variable to count successive invocations
of the same function. This means undo will abort properly on C-g, and
other such interruptions.
This is a lot of diff for a simple-seeming problem. Emacs undo is hard.
