Re: [dev] [st] shift-insert pull request (more general: key.mask and state)

I think my pull request is better. There is no special case for 0 mask and state
and when we match for Ctrl and Shift it works only when they both are
pressed. With your pull request it will work for Ctrl only or for Shift only.

Maybe it can be adopted for dwm so we would be able to remove this
CLEANMASK macro.
