thanks for this;  does that mean that the previous defun for
alt-ess-complete-object-name (distributed in rcompgen package) will
not work in R 2.7.0?  If so, that's a little bit more work, to use the
right defun depending on the version of R.  All doable I think, just
more effort, e.g. to get Emacs to know which version of R is running
within an *R* buffer.  As people like Martin still run multiple
versions of R-x.y.z witin ESS, we'd want to keep this flexibility!
