I think I know why mine is so big.  I did git-gc and git-repack but I
did also git-cvsimport several times and probably on different machines.
Silly me.  That probably duplicated some/most changesets.

I guess everybody can afford 5-10Mb diskspace (+ 3Mb for the working
tree).  This sizes is primarily interesting for the first checkout,
which will be _slower_ than a checkout with CVS.  Later updates will
then hopefully be much more efficient.
