Contrary to what the cc-mode info (4.4 Filling and Line breaking) says,
M-j does not call c-indent-new-comment-line. This makes it impossible,
like I wrote at the beginnig, to get " *" inserted automatically when
pressing M-j to end a line when editing a comment. The result is:

/*
 * Pressing M-j at the end of this line gives
  only a bad indent at the beginnig of this one. Instead of
 * the proper prefix which in this case should be " * ".
 */
