Not exactly -- by removing the -a from the git-repack invocation what
you get is cheap "partial" packing rather than a full repack. This is
somewhat inefficient disk-wise, perhaps by 10% or so. But full repacks
get more and more expensive as the repo grows.

So you don't need to run git-repack -a -d at the end, but it will be a
good measure to see how compact the packing gets.

Yep, I see roughly the same. It grows slowly and I don't know why :(

Cool. If it dies for any reason, just do

  git-update-ref refs/heads/master refs/heads/origin
  git-update-ref HEAD origin
  git-checkout

You only need to do this the first time -- after that, the core heads
are set. Rerun the script and it will pick up where it left. If it
dies again, just do git-checkout to see the latest files.

(Above, replace origin with your -o option if you are using it. I
normally use -o cvshead.)
