It's ok, if you knew a better topic to work on, I'd gladly switch over.
(Given it would be a good beginners topic.)

Looking at the `git log -- git-repack.sh` the last commit is
from April 2012 and the commit before is 2011, so I assumed it
stable enough for porting over to C, as there is not much
modification going on. I'd be glad to include these changes
you're using into the rewrite or the shell script as of now.

So far I have been following the git mailing list, there are
people dreaming of 'everything in C' and apparently those, who
are ok with lots of shell code as well, 'because it's high level'.
I tend to follow the first group, dreaming of everything in C.
Thanks for pointing that out, if it really hurts people from using
git effectively, I'd rather not contribute this patch. But I'd like
to stress again, that the prototying should be done by now.

I asked for a todo wish list a few weeks ago, but got no real answer,
but rather: "Pick your choice and try to come up with good patches".
This is a good policy from the projects point of view (your choice
helps in doing good patches, and good patches do not need as much
review, hence the reviewing costs are low), so I also choose this topic.
