Current CVS trunk on GNU/Linux.

If I have items like:

Emacs.pane.menubar.*.Foreground: Red
Emacs.menu*.Foreground: Blue
Emacs.dialog*.foreground: Green

in my ~/.Xdefaults file, then `emacs -Q' continues to respect these
settings. I expected it to ignore _all_ Emacs-related X resources.
This feature would be more useful if it did so.

Hmm. The only (non-Windows) function I modified to obey
inhibit_x_resources was xrdb.c:x_get_string_resource.

I don't have an X environment. If you can determine which other
functions should be modified, that'd be great.

I forgot to say, using the lucid toolkit (probably relevant).

Yes, the handling of X resources with -Q is imperfect:
the X-resources that affect toolkit elements are still obeyed
(because they access the X-resources more directly, without going
through x_get_string_resource).  That's what you're seeing.

Patches welcome,

Widgets managed by Xt reads resources automatically inside Xt code.
It is considered a feature. You probably can work around this but it  
isn't something as simply not calling a function or setting some  
variable.

Too much work for a small gain IMHO.
