Iʼd call it --without-xdbe, since thatʼs the name of the X
extension. You should probably also add it to the output of configure
(all those "Does Emacs use <foo>" lines), and to
emacs_config_features.

We donʼt do pull requests. Creating a git format-patch (including a
ChangeLog entry), is probably the easiest way to get the change
in. Itʼs possible you'll need to complete a copyright assignment [1]

Eli, would such a change require copyright assignment? I suspect the
change is less than 10 lines.

Regards

Robert

Footnotes:
[1]  Yes, thereʼs a lot of inertia to overcome before you can
     contribute to emacs.
