I like this idea a lot. I will need it when I start getting more work
done on TGDB. However, there is another DRY problem. What functions act
which way for which level?

Basically, should every front end understand that
-file-list-exec-source-files outputs just the files for level 1 but it
also outputs the libraries the files belong to in level2?

One solution could be, for every MI function, we could generate a unique
key. For example, mi1-file-list-exec-source-files,
mi2-file-list-exec-source-files, ...
This key would tell the front end to use that particular parsing
function when checking the output of -file-list-exec-source-files.

Is this to wacky?
