bug#4089: 23.1.50; Emacs Manual Node Persistency Issues

some issues with emacs manual persistency.

Info Node Persistency

... In emacs 22, there's this node:

(info "(emacs)Transient Mark")

but it does not exit in emacs 23's manual.

Shouldn't the manual nodes be persistant across versions, e.g. providing 
redirect when node changed?

As a pratical matter, this means now i have to search my emacs publications 
to fix the nodes. A task that's not particularly trivial. This applies to 
any publication on emacs that reference to the manual by node.

This is a problem with Python's documentation too. thinking about this, 
actually i don't know if there are any manual that:

    * (1) Provide a computable reference to the chapter/sections.
    * (2) Maintain this on different versions of the manual.

However, since emacs does (1) already, it's easy to do (2) too.
