I don't understand.  We're talking about
`Info-goto-node-web', right?  Its purpose
is to visit a manual node in a web browser.

If all you want to do is copy the URL that
the command would use to open that page in
a web browser, then you can do that with a
new command that does just that.

If you're not really talking about what
`Info-goto-node-web' does or is for, then
maybe you should ask for what you want as
a separate enhancement request: an Info
command that copies the URL for a given
node to the kill-ring.

That's not what `Info-goto-node-web' is
about.  Accessing the manual with a web
browser is what the command is about.

You might find what you want to be "more
useful", but this is a command whose job
it is to get you to the manual in a web
browser.

It sounds like what you want should be a
new command.  It's not about copying the
node _name_ to the kill-ring, and it's
not about visiting the node on the web.

Yes, by a loose analogy with
`dired-copy-filename-as-kill' we could
imagine that `Info-copy-current-node-name'
with some prefix arg would copy the node's
URL instead of its name.  The URL can be
thought of as another "name" for the node.

[Dunno why only a zero prefix arg for
`Info-copy-current-node-name' has any
significance.  Odd.
That command isn't in Emacs 20, and in
Emacs 22 the prefix-arg behavior is
already limited to zero.  Maybe it was
introduced in Emacs 21 and other prefix
arg values had some other behavior?]
