Yep... it worked way back with Emacs 19.34, except that you'll always
have the problem with R, which doesn't handle things in the same way.
(ess-search-list) should only be for S-* types, in this case, not for
R.

I think I'd want to do something like replace
	(concat (car ess-search-list)
with
	(concat (if (string= ess-dialect "R")
	            "./"
	         (car ess-search-list))
or similar.  (note - the above is untested code, it gives the flavor,
but I've not compiled nor run it).

As you are supposed to; see ess-vars.el (and ess-source-directory) for 
more details.

I don't see that with R.  With Splus 5.x, it's a known bug.

Yep.  We need to fix that -- the problem is that the "wrong" place
(really, the right place right now) is in the dialect specification
files.

Customize support hasn't been installed.  The catch is that we need to 
still support 19.28--34, making a straightforward upgrade infeasible.

Right, see the fix I provided for this...

Please send to the list!  It'd be great to update the directories...
