Still not defined?

You snipped my main message, about history,
which was to say that accessing such info via
history (e.g. M-p, M-n, M-r, M-s) is more
cumbersome than _completing_ against a set of
choices, which allows not only cycling (M-p/n)
and regexp matching (M-r/s), but additional
ways to match/access candidates directly.

Anyway, it's your enhancement project.  Just
adding this comment about access via history.

Of course, history access can also be enhanced,
including to give access using completion.
