Subject: Info-copy-current-node-name not exact enough

In GNU Emacs 23.0.94.1 (i486-pc-linux-gnu, GTK+ Version 2.16.2)
c runs the command Info-copy-current-node-name
But it is not enough to distinguish some cases, e.g,. when
in (info "(dir) Top") we see
* SC: (emacs-22/sc).            Supercite lets you cite parts of messages
                                  you're replying to, in flexible ways.
* SC (emacs-snapshot): (emacs-snapshot/sc).
                                Supercite lets you cite parts of messages
                                  you're replying to, in flexible ways.

No matter which one we are in, C-u 0 c will just give
(info "(sc) Top"), so there's no command to remember the exact location.
Deeper down, same problem:
(info "(sc) The Built-in Header Rewrite Functions")

If there was a command that would give me "a link to send to my friends
who live on the same machine, that would zero them in to the exact page
of the two possibilities", then at least I can't find it in the menus.
