;; whitespace but by some code as well; so-called code comments. But
;; they are not relevant for the following explanations.)
;;
;; Additionally we are distinguishing two different types of
;; indentation:
;;
;; a) Outer indentation: Indentation before the comment character(s).
;;
;; b) Inner indentation: Indentation after the comment character(s)
;; (taking into account possible comment padding).
;;
;; Comments can be filled syntax-aware or not.
;;
;; In `doctex-mode' line comments should always be indented
;; syntax-aware and the comment character has to be anchored at the
;; first column (unless the appear in a macrocode environment). Other
;; comments not in the documentation parts always start after the
;; first column and can be indented syntax-aware or not. If they are
;; indented syntax-aware both the indentation before and after the
;; comment character(s) have to be checked and adjusted. Indentation
;; should not move the comment character(s) to the first column. With
;; `LaTeX-syntactic-comments' disabled, line comments should still be
;; indented syntax-aware.
;;
;; In `latex-mode' comments starting in different columns don't have
;; to be handled differently. They don't have to be anchored in
;; column one. That means that in any case indentation before and
;; after the comment characters has to be checked and adjusted.

The third element MENU is the name of the submenu where the

nil. If MENU is nil, no menu item will be created.
