Or better to use bindings like in Web browsers: `S-mouse-1' to follow
a link in a new frame, `C-mouse-1' to follow a link in a new window
(or a tab when tabs will be implemented in Emacs).

`Info-mouse-follow-nearest-node' never had the FORK argument.
`Info-follow-nearest-node' still has it, but there were plans to remove it.

This is a question of implementation.  We can implement a command that
will clone the current manual, follow the requested node in a new copy,
and display it accordingly to the command arguments.
