Subject: [PATCH] xinput: req GrabDeviceButton.modifier_device: altenum

add altenum ModifierDevice to field modifier_device for value UseXKeyboard

spec and code:
http://cgit.freedesktop.org/xorg/lib/libXi/tree/specs/encoding.xml#n1195
http://cgit.freedesktop.org/xorg/proto/inputproto/tree/XI.h#n187
http://cgit.freedesktop.org/xorg/xserver/tree/Xi/grabdevb.c#n118

the following spec uses "NULL" instead of "UseXKeyboard":
http://cgit.freedesktop.org/xorg/proto/inputproto/tree/specs/XIproto.txt#n1309
Questions:
* is this spec wrong?
* or does "NULL" have the unusual value of 0xff in this context?
