Hmmmm I rebased after @samuel-gomez merged PR and lost your approval, @arnaudforaison. Sorry.

[youf-olivier]

Le rebase était vraiment obligatoire ?

[gcruchon]

That's my religion, @youf-olivier, I always rebase before submitting a PR.

To me:

• it keeps the history much much much cleaner and more understandable (history being "passive documentation")
• much safer (even more after a 450+ file PR just merged before mine)

De mémoire ca change rien, le merge se débrouille tout seul, mais t'as surement raison.

[gcruchon]

Rebase will make sure commits are one after another... while merges may look like this :-)

Anyway, it's your move to merge it now, I don't have the write-access on this repo :)
