[elpa] externals/exwm f453664bd6: Disable splitting of floating frames (#76)

[ELPA Syncer]

branch: externals/exwm
commit f453664bd6c509a68da6e85242fe941cc64c7b5d

    Disable splitting of floating frames (#76)
    
    Previously, floating frames were configured to never automatically
    split, but they could be manually split (usually by accident).
    
    * exwm-floating.el (exwm-floating--set-floating): disable splitting of
      floating windows by setting a the `split-window' window parameter to a
      function that always throws an error.
