bzr whoami should print error if both username and --email were specified

[Paul Sladen]

Doing:

  bzr whoami --email <email address hidden> 'Paul Sladen'
  bzr whoami 'Paul Sladen' --email <email address hidden>

both give an error:

  bzr: ERROR: extra argument to command whoami:

Okay, fair enough, lets let them one-by-one:

  bzr whoami --email <email address hidden>

however, the output from:

  bzr whoami
  <email address hidden>

then shows that both the clear name and email have been set, despite only being passed --email.

Ideally input and output would have self-consistency.

As indicated by --help, "bzr whoami --email" will only extract and print the current users email address.

"bzr whoami 'Paul Sladen <email address hidden>'" should set your identity.

"bzr whoami --email <email address hidden>" should print an error rather than ignoring --email as it seems to do at the moment.

I'm very sure neither invocation set your whoami for bzr. Its bailing
out in option processing, as appropriate.

bzr whoami --email
 *reports*
bzr whoami 'Paul Sladen <email address hidden>'
would set it

and both are described in the help.

[Paul Sladen (sladen)]

$ bzr whoami
Paul Sladen <[e-mail]>
$ bzr whoami --email '<email address hidden>'
$ bzr whoami
<email address hidden>

Note the successful, error free setting (and the none-display) of the name after the latter invocation.
