Hi Tassilo,

many thanks for installing the patch.  Unfortunately, my last patch
wasn't good enough since I forgot that the ctable package provides a
macro and not an environment.  The patch attached fixes this issue.
This patch hardcodes the search to the environments/macro provided by
the packages "listings", "breqn" and "ctable".  I think this change is
acceptable; any other envs/macros can be added easily by the user and/or
AUCTeX styles.

Best, Arash
