* lisp/erc/erc-track.el (erc-window-configuration-change): New function.
This will allow to track buffer visibility when a command is
finished to executed.  Idea stolen from rcirc.

window-configuration-change-hook.
(erc-modified-channels-update): Remove
erc-modified-channels-update from post-command-hook after update.
