I played with a version of Juri's patch that bound "." to repeat the
repeatable command, and then tried to implement "," to that command passed
-1, but I had a little trouble getting it to DTRT, and then got sidetracked
by a version that used #'repeat instead of this-command.

I mention this mostly to say that the actual ui of last key/./, was pretty
nice in my testing.
