	While your solution is not incorrect, your assumption on the
proposed/given solution from the port is. The '-G' switch appends the
given group to your users already given groups. So, if a user belongs
to groups admin,wheel,test and you run the suggested "pw" command from
the port, your user will now be in groups admin,wheel,test,dialer.
It's the '-g' (lower-case) switch you want to avoid...

	That being said, your suggestion does the exact same thing. So,
really, either works.
