{"they" knew that;  was already needed for ESS 12.04 }

Good!.... I already was working on one, adding it in ess-r-args 
where the other similar functions are.
For that reason, I've also decided to use  ess-r-object-tooltip
(lower case 'r') as the other functions there.

Note that I've added the note, that catching the error message
("not existing object") only works in an English language
locale, and I also put comments there on possibly working
around.

HOWEVER, the "error catching" does not work anyway for me (I do
use an English locale in R), and so I see the error as a
tooltip...
... which is actually ok;
so we could also decide to  drop that whole

  (unless (re-search-forward "\(object .* not found\)\|unexpected" nil t)

  )

check. As I say above, it cannot work in a non-English locale,
*and* it is not so bad if it does not work.  The error message
"as tooltip" is not a problem.

What do you think  (about *dropping* the  'object .* not found'
search) ?
