I do not think that we should bother with eventual problems with users
downgrading individual pacakges, but anyway...

This is superfluous because, by default, any new version of a package
will conflict & replace the previous ones.

In which package we are proposing the above?

At any rate, I think that the right thing to do is to put the following
in jed-common_0.99.18:

    Conflicts: jed (<< 0.99.18), xjed (<< 0.99.18)
