This obsolete commit is completely lost afterwards, which kind of violates the principle of "all changes are kept forever" - should it dump this somewhere for safekeeping?
Also, what if you just don't get rid of the files, and simply remove it from the narrowspec? It'll stop processing/pulling/pushing the directory, but no data is lost.
