Lisp manual text on buffer-local values

Lisp manual text on buffer-local values

[Dave Love]

Node `Intro to Buffer-Local' contains this text with an example
following.  I _think_ it's obsolete in Emacs 21 following changes to
the binding mechanism.  At least the example now behaves differently.

   *Warning:* When a variable has buffer-local values in one or more
buffers, you can get Emacs very confused by binding the variable with
`let', changing to a different current buffer in which a different
binding is in effect, and then exiting the `let'.  This can scramble
the values of the buffer-local and default bindings.

This has been reworded in CVS emacs, and the examples fixed too.

Sorry.  I did check the development version.  I don't know why it
appeared not to have changed.
