	"emacsclient -t" doesn't honor terminal fore- and background colors
Date: Tue, 28 Feb 2012 11:44:48 +0000

First of all, this bug is a duplicate of bug#10748, but I am submitting
this bug report anyway because bug#10748 doesn't seem to receive any
attention from the developers (probably because it doesn't conform to
the Emacs bug reporting rules).

Here is how to reproduce the bug:

1. emacs -Q
2. M-x server-start
3. Open a terminal with nonstandard foreground and/or background colors.
   For the sake of example, I assume that you've run "xterm -bg yellow".
4. Run "emacsclient -t" in the terminal.

The observed behavior: the background becomes grey, whereas the expected
behavior is that Emacs honors the terminal background color.

I normally set the background to white in .Xresources.  I've used yellow
color only to make my point.

This behavior is a regression in Emacs 24.  I've chased it down to this
commit:

commit 27528399fd429b2f510e13f361affb1e2211ceb3
Author: Chong Yidong <cyd <at> gnu.org>

    Fix menu-set-font interaction with Custom themes.
    
    In particular, prevent it from setting non-font-related attributes
    like the foreground and background color.  This requires a bugfix to
    face-spec-reset-face to make "resetting" the default face work.
    
    * lisp/faces.el (face-spec-reset-face): Don't apply unspecified
    attribute values to the default face.
    
    * lisp/frame.el (set-frame-font): New arg ALL-FRAMES.
    
    * lisp/menu-bar.el (menu-set-font): Use set-frame-font.

`face-spec-reset-face' has been changed to reset only non-default faces.
While I understand the rationale of this change, it seems to break
handling of fore- and background colors in terminal.  If I evaluate the
old definition of `face-spec-reset-face' in the *scratch* buffer,
connecting to Emacs with "emacsclient -t" works the way I am used to.

bug#10748 was filed three weeks ago, and there are > 2,000 open bugs.
Duplicating them *on purpose* will not make things better or bugs
fixed faster. If you feel a bug is important and has been neglected,
just comment on the bug's thread with a "Ping", or ask about it in
emacs-devel.

Thanks,

  Juanma
