(whitespace-skipping-not-without-proper-syntax):
Fixes: debbugs:17183
lisp/faces.el (make-face-x-resource-internal): Do nothing when
inhibit-x-resources is non-nil. Don't touch the default face if
reversed video is given--as was done in previous versions of Emacs.
(face-set-after-frame-default): Don't call
make-face-x-resource-internal here.
lisp/faces.el (face-spec-choose): Accept additional optional argument,
whose value is returned if no matching attributes are found.
(face-spec-recalc): Use the new optional argument when calling
face-spec-choose.
lisp/faces.el (face-spec-recalc): Call make-face-x-resource-internal
only when inhibit-x-resources is nil, and do that earlier in the

comment beginning.

lisp/international/characters.el (mirroring): Fix last change:
instead of loading uni-mirrored.el explicitly, do that implicitly
