The output format depends on which command you use. Of course, the
output oif 'port installed' and 'port outdated' differs significantly.
The parameter for those is always an expression that evaluates to a list
of ports.

For example, you could query installation information about all outdated
python modules:

  port installed outdated and 'py27-*'

You cannot switch the output format depending on the input as it is
possible to combine selectors with operators. In the end it is always
just a list of ports.
