Let "git svn" run "git gc --auto" every 100 imported commits, to
reduce the number of loose objects.
To handle the common use case of frequent imports, where each
invocation typically fetches less than 100 commits, randomly set the
counter to something in the range 1-100 on initialization. It's almost
as good as saving the counter, and much less of a hassle.
Oh, and 100 is just my best guess at a reasonable number. It could
conceivably need tweaking.

OK, it didn't feel good saying that. So here's my attempt at being a
model citizen. (It's not hard with a change this small ...)
I'm not quite sure how this should interact with the --repack flag.
Right now they just coexist, except for never running right after one
another, but conceivably we should do something cleverer. Eric?
