Hello !!!

Here is a small patch adding 3 lines of comments to your code, so that other will understand it faster than I did :-)

If that's fine with you, you can set the ticket to "positive review" !

Hi Nathann,

Thanks for your review! The comments were welcome indeed :-)
I rephrased them just a bit, and folded your patch into yours.

No comment on sage-devel, so I guess noone cares.

Cheers,
Nicolas

Great ! This one's good to go ! I wanted to check the documentation again but Sage does not like to have some file added in a branch that disappear in another :-)
