bug#3692: 23.0.95; `i' in Info, when in multiple indexes but same target

emacs -Q
C-h r
i truncate-lines
,

When a matching entry is found in more than one index (or more than
once in the same index), you get a message such as the following:
 
Found `truncate-lines' in Variable Index.  (2 total; use `,' for next)
 
When all of the targets are identical, or even when they are in the
same node, this message is not too helpful. Repeated use of `,' stays
in the same node.
 
On the other hand, it can be helpful to know that the same term is an
entry in both the Command index and the Variable index (for example).
 
It would be good if this behavior could be improved a bit, so that
equivalent targets are filtered in some way, and that you are told
when they are entered in different indexes. I don't have a great idea
about the best way to do that. I just notice that the help that is
given is not as helpful as it might be. So I guess this is a feature
request.
