Describe how to list ignored files

This tip shows how to list all ignored files in a project, which will
take into account not only any `.gitignore` file within a repository,
but also any globally defined list of exclusions such as
`/home/eric/.gitexcludes` and `.git/info/exclude` within the
repository itself.
