[winswitch] capslock acting like shiftlock?

[Thomas Esposito]

"Shift" and "Caps_Lock" aren't exactly the same because the 1st needs to be
held down and the 2nd only needs to be toggled to have the same effect.
Regardless, it sounds like this explains my issue though, because I have a
non-X11 client. Do you know what changed between 1.x and 3.x to cause this?
