branch: externals/exwm
commit f45e9b92731432cd2b01e065d9910321e3a9c9f7
Author: Chris Feng <address@hidden>
Commit: Chris Feng <address@hidden>

    Fix XTerm crash on startup
    
    * exwm-input.el (exwm-input--set-focus): Applications like XTerm
    crashes on receiving WM_TAKE_FOCUS so only send it to X windows
    accepting it.
