Curiously, this breaks for me. It is understandable if we are not
producing byte-for-byte identical output with internal gzip.
With the following hack I can force the step pass, so it seems that
the two invocations of internal gzip are not emitting identical
result for the tar stream taken out of HEAD^{tree} object?
