Just for the sake of completeness (for those who don't use our Debian
GNU/Linux packages).  We have ``meanwhile'' (before we agree on an
official R file standard) simply introduced a one-level hierarchy in
RHOME/data.  The data files that come with the base distribution are in
RHOME/data/base, the new ones in RHOME/data/mlbench etc.

This change requires nothing but changing RHOME/cmd/filename, e.g. as
below.

What would also be nice is to have `make libs' install the data as well
to RHOME/data/$LIBNAME.
