[tex-live] dropped fontspec dependency ?

[Karl Berry]

    Karl, indeed, we need
            collection-xetex
            collection-luatex
    and maybe
            collection-latexrecommended
    to depend on 
            collection-unicodetex

I thought about that, but if we add those engine dependencies, then
anyone installing those packages would end up with both xe(la)tex and
lua(la)tex.  But many people only use one or the other.  So that did not
seem right.

As for latexrecommended, that should not be necessary, if it is, maybe
more things should be rearranged.  Maybe c-latex since all the
unicodetex packages are in fact latex right now, and that's not likely
to change and I can't see that it matters since any installation that
cares about c-unicodetex will already have c-latex.

Sigh.  -k
