- 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.
