I issued the commands to fix the whitespace issue and it doesn't seem to be taken into account by github. I don't know to solve this issue.

Run these commands to correct the problem:
1. `git rebase --whitespace=fix dd0c7a1`
2. `git push --force`

And in my terminal:

>  git rebase --whitespace=fix dd0c7a1
First, rewinding head to replay your work on top of it...

Master is now broken. Please fix.

This issue is that I did not push the changes in the right branch!
Sorry about that. Master should be fixed now. See #290
