It doesn't matter -- we don't have to convert it back.

In freenet,
all files under USK@..../test.git/1/* are packed in a zip file and
must be updated at once.
If we do this, we have to upload all pack files again on every push --
this is very bad.
see http://wiki.github.com/j16sdiz/egit-freenet for more detail reply.
