* exwm-core.el (exwm--mwm-hints): Removed. (exwm--mwm-hints-decorations): New buffer-local variable for indicating whether the X window should have decorations. * exwm-floating.el (exwm-floating--set-floating): Hide the mode-line of undecorated floating X windows by default. * exwm-manage.el (exwm-manage--update-mwm-hints): Set exwm--mwm-hints-decorations; (exwm-manage--manage-window): Manage an undecorated X window if its input model is not 'No Input' or 'Globally Active'.
