Subject: 26.2; outline-hide-sublevels works incorrectly in lisp (elisp, scheme)
 modes -- hides everything regardless of the level
Date: Wed, 28 Aug 2019 23:37:19 +0800

I tested this with `emacs -Q'.
Steps to produce:

1. Visit a lisp file, such as
/usr/share/emacs/26.2/lisp/char-fold.el.gz
2. Type M-x outline-minor-mode
3. Type M-x outline-hide-sublevels

Observe that almost everything is hidden, not just sexps under level 1.
This works even though M-: (outline-level) returns 1 for most of the
lines.

Steps to reproduce 2:
1. Visit a lisp file, such as
/usr/share/emacs/26.2/lisp/char-fold.el.gz
2. Type M-: (outline-hide-sublevels 1)
3. Observe that even more is hidden (everything), even more than in the
previous case.

Why exactly this happens, I am not sure.

Cheers, Lockywolf

I'm not quite sure I understand this bug report -- `M-x
outline-hide-sublevels' hides everything but top-level headings, which
it's supposed to do, I think?

What do you expect to happen instead with that command?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
