Argh.

You don't do that ! IE, dont send a series that

 - Adds something
 - Reverts it
 - Adds a different version
 - Modify it

With barely contains any readable cset.

At the very least the 3 first patches of the series should be squashed.
The two others, if they only change the code just added, as well.
Otherwise they need better descriptions.
