If we want to document how to deal with Z-modules in PARI, probably we
should add a dedicated section on this topic instead of adding bits
of information in unrelated functions help messages. If you want
to compute the intersection of Z-modules, I do not see why you would look
at idealintersect except for the fact that ???"modules" return it.

By the way, ??matintersect still assume that idealintersect can handle
free Z-modules. It should be updated.
