Hello,
With the following c code:
/*-------------------------------------------------------------------------=
----
(c) Copyright notice containing open parentheses
---------------------------------------------------------------------------=
--*/
=20
/*-------------------------------------------------------------------------=
--*/
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
---------------------------------------------------------------------------=
--*/
=20
/*-------------------------------------------------------------------------=
--*/
Note that indenting the comment region removes the problem:
/*-------------------------------------------------------------------------=
----
(c) Copyright notice containing open parentheses
Line containing keyword for
---------------------------------------------------------------------------=
--*/
/*-------------------------------------------------------------------------=
--*/
indents correctly.
Best regards,
Chris

The problem in all these cases which fail is the open parenthesis at
column zero inside the comment. This (currently) causes mis-analysis of
the code around it, as detailed in the Emacs manual on page "Left Margin
Paren".
However, I would be the first to agree with you that this is a fault in
Emacs rather than anything wrong with your source code, which is
perfectly normal C. There is a fix for this problem, and I have some
hope that this fix will be incorporated into Emacs 26.
