Ok, we did not do that in the past, most likely because we were careless
and also we could not imagine  that one day mathwork would renounce its
copyright.

The question is should I «rewrite» the repository changing commits and
trying to add the name of the authors before it will, hopefully one day
enter ELPA?

(I think I can do that in mercurial with the evolve extension and then
try to push that locally with the hg-git extension to the local git
repository). That might however mess up things.
