It is possible, that some minor piece of code was badly tracked, for
some reasons (SVN, mainly) or that some small developers did not answer.
However, as an "œuvre collective", defined as in "CPI 113-2 alinéa 3",
and seeing "Cour. Cass. 17 Mai 1978", and seeing that the editor and
the very vast majority of developers have agreed (> 99.99% of the code,
> 99% of developers), we are fine here.
