The behaviour in the example below looks correct to me since passwd
contains lines that don't match your expression. It sounds like you
are proposing a new option to invert printing of file names.

To date, the general policy (imposed by senior people on the list,
whatever that means) was not to introduce new functionality to grep that
can be accomplished using other standard *nix tools.
