Make error for empty config a little friendlier

In the setup guide in the README, we have people start out with an empty
file (created using `touch`). Before this patch, Dotbot gave the
following error:

    Configuration file must be a list of tasks

Instead, with this patch, Dotbot says:

    Configuration file is empty, no work to do
