Fix documentation for apt-get-sqq parser

[kellyjonbrazil]

The documentation would be better with something like this as an usage example:

$ apt-get -sqq upgrade | jc --apt-get-sqq

or

$ jc apt-get -sqq full-upgrade

Missing out upgrade or dist-upgrade or full-upgrade from the command results in a command that fails:

apt-get -sqq 
E: Command line option 's' [from -sqq] is not understood in combination with the other options.
