It is about "comment-start".  I am constructing a "regexp" for use with hi-lock mode to highlight certain comments.

For elisp I am matching ";; [Text] More"

The regex is adapted for the particular programming mode.  Another difficulty has been that in "c-mode", "comment-start" returns "/*" with no possibility to get the alternative "//". 

(defun tegor ()
  "TODO."
  (interactive)

  (let ( (fm (format "%s%s" comment-start comment-start)) )

    (message "fm: %s" fm)
    (message "kmcategor: %s"
       (format "%s%s%s" "^\s*" fm "\s\\(\\[.+\\]\\).*$"))))
