Subject: [PATCH 189/189] telemetry: make help command more helpful
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The /help telemetry command prints out the help text for the given
command passed in as parameter. However, entering /help without any
parameters does not give any useful information as to the fact that you
need to pass in a command to get help on. Update the command so it
prints its own help text when called without any parameters.
