changes on “info” function in emacs 23

[Xah Lee]

in emacs 22, when in info inside emacs, if i press “c”, i get the node
info in my kill ring, for example:

(elisp)System Environment

But in emacs 23, i get:

(elisp) System Environment

is there any explanation or doc about this change? I don't see it in
the NEWS file.

this seems important to me because programatically, i can do eval in
elisp:

(info "(elisp) System Environment")

to get emacs to display the node.
It still works with or without the space, but would like to read about
this change.

thanks.
