I've investigated a bit, and the main problem seems to be that for git commits that extend over several directories, the commit message is duplicated into many ChangeLog entries. For example, the message of the initial commit 56bd759 appears in some 18000 files, which accounts for 25 MiB. Then there is commit eaaface and its revert 1bfb585, again appearing in almost all ChangeLog files in the tree. These account for another 9 MiB. Last example, commit 8849b09, another 2 MiB. So about 70% of the size is caused by these 4 tree-wide commits alone. However, there are many more examples of duplication on a smaller scale. Ulrich
