bug#56820: outline-minor-mode replacing the first character with an arrow

[Yilkal Argaw]

Hi Guys,

Today I compiled emacs from source and while using outline-minor-mode
it started replacing the first character with an arrow whenever I fold
the code. The characters remain  as arrows even when I disable outline
minor mode. To recreate the issue

   + emacs -q
   + open a source code file (I opened ruby,  python and elisp files)
   + outline-minor-mode
   + M-: (set outline-minor-mode-cycle t)
   + (outline-minor-mode-cycle-buffer)

The emacs version I use is   29.0.50 (build 4, x86_64-pc-linux-gnu)

wiith regards
Yilkal A.

Hehe, and in compile buffers there are icons now, too!

I guess at least that is wrong.

FWIW, I also see the bug (?) that a folded outline heading has a
down-arrow symbol while an unfolded one has just an empty square with
border.  I would assume it should have a right-arrow icon.

Please remove emacs-devel from the CC list when responding, so that
this discussion is kept on the bug tracker/list only.

Thanks.

Is this an approximation to the  "twister" isosceles triangle UI idiom:
* folded: vertical base, rightwards-facing
* unfolded: horizontal base, downwards-facing

Are the glyphs clickable?

Yes, they are.
