bug#8745: Enhancement Request: Support for restricted bash interpreter scripts

[David Michael]

Hi,

  When bash is invoked with the name "rbash", it starts a restricted
shell (same as "bash -r").  This interpreter name is not recognized
and therefore sh-mode is not enabled when editing restricted scripts.

  The following patch is specifically what I am requesting.

 Thanks
