Git: show total file size difference between two commits?

Question

Is it possible to show the total file size difference between two commits? Something like:

$ git file-size-diff 7f3219 bad418 # I wish this worked :)
-1234 b

Expanding on matthiaskrgr's answer, https://github.com/matthiaskrgr/gitdiffbinstat can be used like the other scripts:

gitdiffbinstat.sh HEAD..HEAD~4

Imo it really works well, much faster than anything else posted here. Sample output:

$ gitdiffbinstat.sh HEAD~6..HEAD~7
 HEAD~6..HEAD~7

 Recursively getting stat for path "./c/data/gitrepo" from repo root......
 105 files changed in total
  3 text files changed, 16 insertions(+), 16 deletions(-) => [±0 lines]
  102 binary files changed 40374331 b (38 Mb) -> 39000258 b (37 Mb) => [-1374073 b (-1 Mb)]
   0 binary files added, 3 binary files removed, 99 binary files modified => [-3 files]
    0 b  added in new files, 777588 b (759 kb) removed => [-777588 b (-759 kb)]
    file modifications: 39596743 b (37 Mb) -> 39000258 b (37 Mb) => [-596485 b (-582 kb)]
    / ==>  [-1374073 b (-1 Mb)]

The output directory is funky with ./c/data... as /c is actually the filesytem root.
