I'm guessing you do this with filter-branch right?

Here is the problem. Before you could push with test_clone2 you probably 
had to pull first. Because the latest commit ID's did not match (because of 
filter-branch), the 2 commits are merged together. And presto, the big-file 
is merged back. Now push, and the big-file is back in the upstream branch.

This can be avoided, but you have to do that manually in every repo that 
has the big file cloned. Do as follows:
Fetch the upstream changes (git fetch) (so you get the upstream branch 
without the big file)
Reset the current branch to the upstream branch (git reset --hard 

When there were already changes made that needed to be pushed, you have to 
cherry-pick those changes. The easyest way to do this is via the gui.
gitk HEAD@{1}
Right-click a change to be cherry-picked, and select cherry-pick.

When done, you can push again. And repeat the steps for every clone.

Yep, its been merged in by test_clone2

For many users you have to tell them what to do to get rid of the big file. 
Or hand them a script that could do it for them.

Good luck!
