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
This change was prompted by
https://github.com/anishathalye/dotbot/pull/226.
