Calling client_add_key as follows

  client_add_key -

will fail. However using an explicit -shared option, like this:

  client_add_key -shared -

will succeed. This is caused by a failure to parse the - key token, which is
mistaken for the first character of an option argument.

The client_add_key command also returns a spurious "success" message when a
malformed option is supplied.

This patch fixes both issues.
