Running --grid with the latest git version of zetta is broken on my machine.
E.g. by doing cargo run --release -- --grid, or using an installed version (see screenshot below).

This is a fairly severe regression as the the default expected behavior of exa/zetta is to run --grid if nothing else is specified.
