I agree, I think that may be a worthwhile change. I was a little
surprised it didn't do that already and appears to silently fail if
Source: isn't set (or we fail to check the exit code).

I also have found out some people are using this Source: data to find
recipe information so we likely do need some way to map it back to the
recipe, I'm hoping the filename is good enough for that purpose...
