Subject: [PATCH] base-files: make wifi report unknown command
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Avoid having /sbin/wifi silently ignore unknown keywords and execute
"up"; instead display the help message and exit with an error.

Spell out the "up" keyword (which has users), add it to usage output,
and preserve the implicit assumption that runing /sbin/wifi without
argument performs "up".
