+ * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
+
+ * xterm.c: Declare x_handle_net_wm_state to return int.
+ (handle_one_xevent): Check if we are iconified but don't have
+ _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
+ (get_current_wm_state): Return non-zero if not hidden,
+ check for _NET_WM_STATE_HIDDEN (Bug#9893).
+ (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
+ (x_handle_net_wm_state): Return what get_current_wm_state returns.
+ (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
