[ESS-bugs] ESS 13.09-1 with old R versions fails pretty badly

[Martin Maechler]

I've worked on this,  but got "hung up" on the FIXME in
     ess-r-d.el
to autogenerate the ESSR package version number used there,
and committed my current changes... should be working but
are unfinished, notably for the first simple workaround source()
workaround.

More is planned in two days only (as I have to prepare other
stuff urgently for Thursday morning and am already busy with
something else a big part of tomorrow).
