bug#10787: 23.4; hs-hide-* functions don't honor page break in Emacs-Lisp major mode (and probably others too)

[Bruno Félix Rezende Ribeiro]

Suppose that you have a buffer with Emacs-Lisp major mode and hs minor
mode enabled and into it a piece of code like this: (where ^L indicates
page break)

--

;; here is only a foo comment for a commented bar function
;; (defun my-bar-function () nil)

^L
;; here is another foo comment for another commented bar function
;; (defun my-second-bar-function () nil)

--

Now, if you run hs-hide-all command the text appears like this:

--

;; here is only a foo comment for a commented bar function...

--

It's very annoying.  I often comment consecutive functions and
hs-hide-all don't honor sequential newlines.  So, I was breaked page
hoping that my functions were kept separated.  But that didn't happen.
This bug report is to suggest developers to make hs-hide-* functions
respect page breaks for this and others major modes too.

Thanks for your attention.

This was reported 7 years ago, but never got a reply at the time.

I can't reproduce this on current master.  Are you still seeing this
on a modern version of Emacs?

If I don't hear back from you within a couple of weeks, Ill just close
this bug as unreproducible.

Best regards,
Stefan Kangas

Hi Bruno Félix,

The below email bounced when trying to send it to oitofelix@gmail.com.
I'm therefore resending this to what I guess is your new email
address.

Best regards,
Stefan Kangas

More information was requested, but none was given within 4 weeks, so
I'm closing this bug as unreproducible.  If this is still an issue,
please reply to this email (use "Reply to all" in your email client)
and we can reopen the bug report.
