Gracefully handle xmodmap -e "clear mod4" #655

Gracefully handle xmodmap -e "clear mod4"

My init file has some bindings on the super key (as below). It has a mix of standard and my own functions.

When I try xmodmap -e "clear mod4", I see [XELB ERROR] (wrong-type-argument number-or-marker-p nil). The debug log shows a stacktrace when handling the s-c key. (s-c is the first of the keys in exwm-input-global-keys and is bound to my own custom command).

Once the above error happens, some of the keys on my keyboard stops working and for all practical purposes the laptop becomes useless. I have no other go, but to logout and login again.

Kindly handle the error gracefully so that my system remains usable.
