+Subject: [PATCH] cmd/button: return button status
+
+To make the button command useful in a shell script it should return the
+status of the button:
+
+* 0 (true) - pressed, on
+* 1 (false) - not pressed, off
+
+The button command takes only one argument. Correct maxargs.
+
+Adjust the Python unit test.
