Hi, Ihor, thanks for your comments,

My first approach was actually to define some options for
org-babel-process-comment. But I noticed that a header with properties,
for example:

* Header
  :PROPERTIES:
  :FOO:      var
  :END:

is interpreted as:

;; Header
;; :FOO: var

I think the culprit is the '(match-end 0)' in
org-babel-tangle-single-block:

...
(comment
	  (when (or (string= "both" (cdr (assq :comments params)))
		    (string= "org" (cdr (assq :comments params))))
	    ;; From the previous heading or code-block end
	    (funcall
	     org-babel-process-comment-text
	     (buffer-substring
	      (max (condition-case nil
		       (save-excursion
			 (org-back-to-heading t) ; Sets match data
			 (match-end 0)) ;; <=========
		     (error (point-min)))
		   (save-excursion
		     (if (re-search-backward
			  org-babel-src-block-regexp nil t)
			 (match-end 0)  ;; <=========
		       (point-min))))
	      (point)))))
...

So I couldn't think of any other solution than to put the change there,
so as not to break backwards compatibility. But it is a somewhat tricky
solution...

Best regards,

Juan Manuel
