In terms of the specification at http://www.opengroup.org/onlinepubs/009695399/utilities/who.html, we're required to support "am I" and "am i". We're doing that. But there is no standard interpretation of any other non-option arguments. Hence the current behaviour is allowable, but if I understand you correctly you're just pointing out that it is surprising. I guess it is, really. I'm not really sure though on what grounds we should restrict the allowed arguments, or how we should explain the new restrictions to the user.
