Buffer-menu-revert-function

Buffer-menu-revert-function

[Luc Teirlinck]

When you enable autoreverting of the Buffer Menu, the current buffer
looses the `.', that normally gets prepended to it.  This is
especially bad if you elect to sort the Buffer Menu in some order
other than visited order.

The reason is that `Buffer-menu-revert-function' has to be called with
*Buffer List* as the current buffer.  The same problem would occur
whenever any Lisp function calls `Buffer-menu-revert-function'.

The patch below fixes this.  I will install if there are no objections.
