Lots of people agree with that rule ;-).

? There is no problem with indentation here, is there?  What you seem
to want is automatic insertion of line ends for wrapping.  cc-mode
doesn't do that, I admit.  I'm not sure I would want it either.

With my settings and adding the missing parentheses to your code I get

        if (ReallyLongFunctionName(
                    AnotherReallyLongFunctionName(
                            "a really long string constant")))
        {
        }

Which is pretty near to what you seem to want.  I did have to add line
breaks manually, of course. 


so long, benny
