; Coding style fixes * exwm-core.el (exwm-mode-menu exwm-mode-map): Use `exwm-workspace--count'. * exwm-workspace.el (exwm-workspace--set-fullscreen) (exwm-workspace--on-focus-in, exwm-workspace--set-desktop): Use `exwm-workspace--position'. * exwm-workspace.el (exwm-workspace-swap, exwm-workspace-move): Renamed from `exwm-workspace-swap-workspace' and `exwm-workspace-move-workspace'. * exwm-workspace.el (exwm-workspace--update-ewmh-props): Update comments. * exwm-workspace.el (exwm-workspace--switch-map-nth-prefix): Fix a calculation. * exwm-workspace.el (exwm-workspace-switch): Fix a potential timer problem. * exwm-workspace.el (exwm-workspace-swap, exwm-workspace-move) (exwm-workspace--remove-frame-as-workspace): Update workspace and clients involved. * exwm-workspace.el (exwm-workspace--remove-frame-as-workspace): Remove workspace first.
