M-x kill-node is useless

[Gavin Smith]

In standalone Info, there is a command "M-x kill-node" which is
supposed to be used to forget about nodes that are being viewed or
have been viewed. However, it doesn't work, and isn't useful anyway.

It can only be used to kill nodes that are currently being displayed,
and not in the history of a window. There's no way to distinguish
between nodes with the same name. Also, there's also a check in the
kill_node function that we're killing a node in the current window
(the ChangeLog says this was added in May 1998). For example, with
info 5.2, try "info bash" followed by "C-x 2 mintro<ret> C-x o
mdef<ref> M-x kill-node<ret><tab>". You get the options "Definitions
Introduction". Type "Intro<tab><ret>". Then you get the error message
"Cannot kill node `Introduction'".

Is it okay to remove this command?
