[Message part 1 (text/plain, inline)]

Hi,

When I use emacs 24.3.1 and run

  /usr/bin/emacs -Q

Then M-< followed by M-x global-hl-line-mode and M-x describe-face, emacs asks 
me

Describe face (default `font-lock-comment-delimiter-face'):

But when I use 26.1 and run

  /usr/local/bin/emacs -Q

and run exactly the same commands, emacs asks me

Describe face (default ‘hl-line’):

I have to turn hl-line off to get the name of the point's face. This makes the 
default value of the function useless.

It seems that

  (get-char-property (point) 'face)

returns hl-line in 26.1, but returns the actual face in 24.3.1.

Thanks,

Ch.

I can reproduce this, but for me both Emacs 26 and Emacs 24 behave the
same.  So I don't know why your Emacs 24 behaves differently, perhaps
it's due to some local changes that are not in upstream sources.

In any case, "M-x describe-face" is not the right tool when there
could be several text properties at the same position, because
describe-face can only name one face, and it selects the one that
affects the text the most.  I suggest to use another command instead,
"M-x describe-text-properties".  It will pop up a window with
information about all the properties at point, and you can then drill
down using the buttons in that window.

This is not a bug.

Thanks.
