Hello,

With the following c code:

/*-----------------------------------------------------------------------------
(c) Copyright notice containing open parentheses
-----------------------------------------------------------------------------*/

 /*---------------------------------------------------------------------------*/


the last line is indented incorrectly, as the identified syntactic
information is ((topmost-intro-cont 1) (comment-intro)). I think it
should be ((topmost-intro 1) (comment-intro)), which the following code
correctly identifies:

/*-----------------------------------------------------------------------------
Non parenthesis language
-----------------------------------------------------------------------------*/

/*---------------------------------------------------------------------------*/


Similarly, if there is a keyword in the comment, the next comment is
incorrectly identified and indented:

/*-----------------------------------------------------------------------------
(c) Copyright notice containing open parentheses
Line containing keyword for
-----------------------------------------------------------------------------*/

                        /*---------------------------------------------------------------------------*/

Note that indenting the comment region removes the problem:

/*-----------------------------------------------------------------------------
  (c) Copyright notice containing open parentheses
  Line containing keyword for
-----------------------------------------------------------------------------*/

/*---------------------------------------------------------------------------*/

indents correctly.

Best regards,
Chris
