Yes, this will make the environment behave like an  alltt  environment,
and respect spaces, etc.
However, macros will be expanded as \ remains with its escape-char
interpretation.


Also, it really ought to be:

     $alltt_rx .= '|AAApreform|BBBpreform';

or (just to be safe):

    $alltt_rx = ($alltt_rx ? $alltt_rx.'\' : '' ) . 
'AAApreform|BBBpreform';



If you want it to be a real 'verbatim-like' environment, for 
program-listings
where '\' has a different meaning, then there's a lot more work to do.

There should be a recent message from me on this list about this,
and the need to catch the environment by hacking the  texexpand  script.

And this too.
