commit 83b9f570009b665f407032ff382746835847393d

    Exclude `project.yml` as rev-depgraph node key
    
    This commit changes the debug log output.
    
    Nothing ever depends on `project.yml`, so don't include it as a node key
    in reverse dependency graphs.  This change removes some zero-information
    lines from the debug output.
