Yeah, I was talking about something similar that could be used with
Bart's new smart-insert-last-word widget.  Seems like some common ability
to match and filter history would be useful in several situations.  Sort of
a regex for command history... 8)

Another thing I would use is a "soft" or "fuzzy" history mechanism.  For
example, I would really like to be able to intercept a "!$" history option
and replace it with a call to smart-insert-last-word (w/command line matching).
Or the ability to intercept other history calls like !* or !!.  It seems like
it would be useful to have an option that would allow us to play with this
history mechanism, so it's a little more DWIM.
