[hackers] [st][PATCH] Add 14th bit to XK_SWITCH_MOD bitmask

From: <petarkapris_AT_firemail.cc>
Date: Sun, 18 Jul 2021 00:14:00 +0200

From: Petar Kapriš <petarkapris_AT_firemail.cc>

The bits of uint signal in an XKeyEvent which concern the key group (keyboard
layout) are bits 13 and 14, as documented here:
https://www.x.org/releases/X11R7.7/doc/libX11/XKB/xkblib.html#Groups_and_Shift_Levels
In the older version, only bit 13 was marked as part of XK_SWITCH_MOD, this
causes issues for users who have more than two keymaps. the 14th bit is not
in ignoremod, key sequences are not caught by match(), if they switch to a third
or fourth keyboard.
