Just to comment on this possibility; I see an option, given the
definition of ED and EROOT to do Prefix without them, by e.g. using
${D}${EPREFIX} instead of ${ED} as shorthand.  When ${EPREFIX} would be
unset, this would result in simple ${D}, which is "backwards
compatible".  This is not all what is necessary, but a big deal of it.

Question here, however, is whether this is worth it.  Personally, I
prefer the shorthands, as they give a lot of readability.
