This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug. If you can, give
a recipe starting from `emacs -Q':
In *scratch*:
(face-attribute 'italic :slant)
italic ;; Good.
(face-italic-p 'italic)
(italic oblique) ;; Fine.
(assq :slant (face-all-attributes 'italic))
(:slant . unspecified) ;; Say what??
In fact face-all-attributes gives me unspecified for all attributes in
the faces I tried (about 5), including the default face.
Did I misunderstand how face-all-attributes work?

This happens because face-new-frame-defaults has `unspecified' for all
the attributes of `italic' face (and all other faces as well). Try
(face-all-attributes 'italic (selected-frame))
and you will get what you expect.

I don't know, but it sounds like the doc string is at least misleading
in this regard. OTOH, this function is not used anywhere in Emacs, so
it could be buggy.
What is your use-case, exactly?

Just trying to get all attributes for a possible conversion to pango markup.
I intend to use it for tooltips so Emacs can use the system tooltips instead
of its own. In principle it is possible to put properties on the tool tip
string so I'm trying to handle that. Maybe this is overkill, most toolstips
in Emacs are straight strings, but I've seen bold and italic. I can ask for
specific attributes instead of using face-all-attributes.
An improvement for the documentation would be to refer to face-attribute and
say that if frame is nil or omitted, face-attribute is called with frame
argument t.

Cc: 6767-done
I made the function documentation more like the texinfo documentation.
