PATCH: HISTNO zle parameter

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

This adds the `HISTNO' zle parameter giving the current history
number. It is readonly.

This also makes `NUMERIC' settable, which was already there, but
disabled due to the `PM_READONLY' in the table. Ahem.

It also make `_list' use `HISTNO'.

Bye
 Sven
