CC Mode 5.33.2 also indents "Emacs 22-style", i.e. to 5 columns, but the
current sources, AFAICS, are indented to 2 columns, "Emacs 21-style".

Shouldn't the now-existing c-lineup-gnu-DEFUN-intro-cont be changed
accordingly, to indent to 2 columns instead of 5?

I too have yet to notice a problem with other macros.
