Here are 6 bugs (or at least changes that might need to be
documented) in Org commenting and filling.
Context: commenting and filling used to use generic Emacs
facilities, but now use Org-specific ones.
original:
===
x
bug 1: the line above now does not get commented even if
comment-empty-lines is t.
bug 2: this line now does not indent consistently with the
rest of emacs.
===
comment-dwim:
===
# x
# bug 1: the line above now does not get commented even if
# comment-empty-lines is t.
# bug 2: this line now does not indent consistently with the
# rest of emacs.
===
bug 3: outside of org with filladapt turned OFF, filling this
paragraph does not
indent it. also auto-fill
indents unlike the rest of emacs. ret tab is ok.
#bug 4: this paragraph now gets exported in HTML subtree
#export, which will likely surprise many people who formerly
#used "#" comments instead of "# " comments and don't
#carefully check all output. they might
#even publish private information automatically without
#realizing it using old files that they forgot or did not
#know to convert.
#bug 5: filling this paragraph with "===" on the following
#line will fill the ===, unlike the rest of emacs with
#filladapt turned ON. we are supposed to not use filladapt
#with org. therefore, how do you emulate the filladapt
#behavior so that there is consistency between emacs and
#org?
Bug 6: what does the Org-specific commenting do? i was not
able to determine that from the docstring to
org-comment-or-uncomment-region. maybe update docstring
would help others trying to find out why commenting works
differently in org from the rest of emacs?
Hope it helps.
Thanks.

Both fixed.

Fixed.

This has been announced in 7.9 changes.

I don't know filladapt.el. I've done my homework, though, and looked at
the file.
If you want to use filladapt.el, you'll have to tweak
`filladapt-token-*' variables. If you come up with a working setup,
please put it on org-hacks.org as some users may appreciate it.
For example, `cc-mode' does it in `c-setup-filladapt' function.

I don't think such explanations belong to
`org-comment-or-uncomment-region' docstring. Though, I have dropped
a note in org.el:
Org comments syntax is quite complex. It requires the entire line to
be just a comment. Also, even with the right syntax at the beginning
of line, some some elements (i.e. verse-block or example-block) don't
accept comments. Usual Emacs comment commands cannot cope with those
requirements. Therefore, Org replaces them.
Org still relies on `comment-dwim', but cannot trust
`comment-only-p'. So, `comment-region-function' and
`uncomment-region-function' both point
to`org-comment-or-uncomment-region'. Eventually, `org-insert-comment'
takes care of insertion of comments at the beginning of line.
I hope it is clearer now.
Thanks for the detailed report.

As a user, what is the best way in both the old and new exporters to
remove #[^+] lines on export? Flush lines in one of the hooks? Or is
there a setting?
Or error if there are any such lines in the exported subtree. (I
always export subtrees.) Is this possible?

filladapt worked as it does in the rest of Emacs until pretty
recently, but it stopped working (error) when Org changed filling.
This bug refers to how Org without filladapt works.
Are you suggesting getting it to work again, then fixing this bug? My
concern is that further changes in Org might make it not work again.
The alternative is to make the Org behavior work as it used to with filladapt.
> I hope it is clearer now.
Yes, thanks for explaining that it is for comment and verse blocks.
> Thanks for the detailed report.
Thanks for addressing the bugs.

You can flush such lines in a hook:
#+begin_src emacs-lisp
(defun my-flush-old-comment-syntax (backend)
(while (re-search-forward "^#[^ \t+]" nil t)
(when (memq (org-element-type (org-element-at-point))
'(paragraph verse-block))
(delete-region (line-beginning-position)
(progn (forward-line) (point))))))
(add-hook 'org-export-before-parsing-hook 'my-flush-old-comment-syntax)
#+end_src
> Or error if there are any such lines in the exported subtree. (I
> always export subtrees.) Is this possible?
For a warning, you may want to have something like:
#+begin_src emacs-lisp
(defun my-old-comment-syntax-warning (backend)
(when (re-search-forward "^#[^ \t+]" nil t)
(or (yes-or-no-p "Document may contain old-style comment syntax. Still proceed? ")
(error "Export aborted"))))
(add-hook 'org-export-before-parsing-hook 'my-old-comment-syntax-warning)
#+end_src

If the error, which you haven't reported yet, happens when using
filladapt, then filladapt has to be tweaked.

I am probably misunderstanding "bug 5". May you describe it again along
with both the expected and actual behaviour in the situation?

Thanks. I like your yes or no p idea.

It works now.

What hook in the old exporter would be the closest equivalent?

Thanks.

Not equivalent, but close enough: `org-export-preprocess-hook'.
