Student project in Ensimag: thanks all!

Hi,

For the third year, I offered my students to contribute to open-source software as part of a school project. This year, we had one team on the core of Git (who implemented better advices for "git status", the XDG configuration directory, and "git rebase -i --exec"), and two working on the Git-mediawiki interface (one worked on new features like support for mediafiles and authentication using the git credentials mechanism, and another on an automated testsuite).

The project itself ended a while ago, but some of the patch series needed extra care to end up in pu. This is now done :-).

A few series have been abandoned ("bisect old/new", and "warn before rebase/commit"), I've added pointers to the gmane threads on the page https://git.wiki.kernel.org/index.php/SmallProjectsIdeas in case someone wants to continue the work.

To conclude the project, I would like to thank everybody for their participation: the students for their hard work, reviewers for their support and patience, and of course Junio for being such a good maintainer!

Looking forward to next years' project!
