Well, the workaround does not help much.  The source files will be 
copied to the new package, but they are not evaluated (because 
package.skeleton requires list= to be missing).  Therefore you won't 
have the documentation files reflecting the contents of essai.r

So, for the moment, this just seems to be a bug needing fixing.  Merci 
et ne quittez pas.
