For reference, 20 years of Perl with very deep deltas:

wilber:~/src/perl-preview$ du -sk .git
73274   .git
wilber:~/src/perl-preview$ git-repack -a
Counting objects: 244360, done.
Compressing objects: 100% (55493/55493), done.
Writing objects: 100% (244360/244360), done.
Total 244360 (delta 181061), reused 244360 (delta 181061)
wilber:~/src/perl-preview$ du -sk .git/objects/pack/
75389   .git/objects/pack/
wilber:~/src/perl-preview$

There are a few generated files in this history, but really only yacc
files etc.  It is in general also a lot of small changes.
