Yes, I agree that this needs a more robust approach. Also, I've noticed
that the patch I've proposed has a rather silly bug: replacing the
second `match-end 0' with `match-beginning 0' naturally causes
intermediate code blocks to be exported as comments (!). Returning it to
`match-end 0' everything is OK, but the present approach is still

I'm going to see if I can try something cleaner these days. Ideally,
everything should be controlled from org-babel-process-comment-text...

On the other hand, I have a curiosity. I understand that the behavior of
the `:comments org' option should be left intact to ensure backwards
compatibility. But I've always wondered if there is any use case where
this value, as it behaves, might be practical. I don't quite understand
how useful all the Org metadata in the comments of the tangled file can
be. The expectation with `:comments org' is that only the content of the
Org document will be rendered (as comments), but not its metadata, that
all they do is unnecessarily fatten up the source file. I'm thinking,
for example, of headers with lots of properties. or comment blocks,
which would be visible in the tangled source file:

│ ;;   Header
│ ;;   :A_LOT_OF: properties
│ ;;   :END:
│ ;; #+begin_comment
│ ;; Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Donec hendrerit tempor tellus.
│ ;; Donec pretium posuere tellus. Proin quam nisl, tincidunt et, mattis eget, convallis nec,
│ ;; purus. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus
│ ;; mus. Nulla posuere. Donec vitae dolor. Nullam tristique diam non turpis. Cras placerat
│ ;; accumsan nulla. Nullam rutrum. Nam vestibulum accumsan nisl.
│ ;; #+end_comment

Best regards,

Juan Manuel
