Yes, see my other post.

Again, see my last post. But the mental model of "git stores objects"
gives you a nice upper bound (I hardly ever run 'git gc').
I really don't think that diffing (or not) is the problem here. The main
reason why git repositories tend to be larger than subversion
repositories is that a checkout will give you a local copy of the whole
project history, which I consider a big benefit ('git log'vs. 'svn log'
while being offline). But does this really create bloat? My (over)simple
back-of-the-envelope calculation for the curren svn:

 - 34 versions of the heap image
 - image size 26Mb -> zlib compressed 6Mb
 => (* 26 (* 33 6)) = 224

 That's not really that much of a bloat, isn't it?
