Not by a factor of ten. |

I've investigated a bit, and the main problem seems to be that for git |
| 16 |
commits that extend over several directories, the commit message is |
| 17 |
duplicated into many ChangeLog entries. |
| 18 |
|
| 19 |
For example, the message of the initial commit 56bd759 appears in some |
| 20 |
18000 files, which accounts for 25 MiB. Then there is commit eaaface |
| 21 |
and its revert 1bfb585, again appearing in almost all ChangeLog files |
| 22 |
in the tree. These account for another 9 MiB. Last example, commit |
| 23 |
8849b09, another 2 MiB. |
| 24 |
|
| 25 |
So about 70% of the size is caused by these 4 tree-wide commits alone. |
| 26 |
However, there are many more examples of duplication on a smaller |
| 27 |
scale. |
