Some options (in particular, -g) are processed immediately upon being
parsed. This will produce the wrong result in combination with -j since
we only attach to the jail after we're done parsing arguments. Solve
this by attaching to the jail immediately when -j is encountered. The
downside is that e.g. ifconfig -j foo -j bar would previously attach
to jail “bar”, whereas now it will attempt to attach to jail “foo”, and
if successful, attempt to attach to jail “bar” within jail “foo”. This
may be considered a feature.
