Merci j'ai poussé la branche sur master (87e595901).

Make sure all the numbers have similar orders of magnitude, i.e. avoid
this:
?  lindep([zetamult([2,2,3]),zetamult([2,3,2]),zetamult([3,2,2]),zeta(7)*2^100])
%36 = [-513287312954585225304414910147,947245740281189247870102556492,780733460572008810439478573835,0]~

One trick I can offer is to add 'exp(1)' to the list and check whether
its coef is zero.

? lindep([exp(1),zetamult([2,2,3]),zetamult([2,3,2]),zetamult([3,2,2]),zeta(7)])
%37 = [0,528,672,352,-151]~


0*exp(1): Probably OK.
