PATCH: 4.0.2: rprompt2 variable

[Derek Peschel <dpeschel@eskimo.com>]

Even if a feature (right-hand prompts) is frivolous, it might as well be
available in general.

Now you can see the parser state (or whatever else you might want to put
in PROMPT2) and still have a consistent left margin when entering a multi-
line command.  See my companion "reverse parser state" patch if you want
the parser state to expand leftward on your screen.

Comments welcome (I just started using zsh and I have no idea if anyone
else will find these patches useful).
