[AUCTeX] Make AUCTeX aware a new verbatim environment

[Leo]

Hi there,

I use listings to define an environment like this:

\lstnewenvironment{latex}[1][]
{\lstset{language={[LaTeX]TeX},#1}}
{}

However, AUCTeX didn't recognise it as a verbatim environment leaving me
accidentally adding space in it, which then was included literally. It
will be very helpful to get the visual hint if AUCTeX can treat it like
the verbatim environment. Ideas?

Thank you.
