Fixed a couple of serious bugs.

Detail:
  Session command handler function pointer was being left uninitialised.
    If you were lucky, it data aborted ...
  When preformatting output with vsprintf, it's not a great idea to pass
    the destination buffer as one of the substitution strings, otherwise
    it disappears up itself and generates a puff of smoke.
Admin:
  Tested with CLI_App.
