ERC 5.2 stable pre-release synced to Emacs 22 source tree

[Michael Olson]

I've merged in several changes from the main ERC development branch,
including several bugfixes.  The version of ERC in Emacs 22 is now
"5.2 stable pre-release".  This will probably be the last change to
the version of ERC in Emacs 22 before the release, pending any
bugfixes.  For details on the changes, see the lisp/erc/ChangeLog
file.

Note that ERC is now invoked with M-x erc, not M-x erc-select.  If you
were using the old `erc' function programmatically, use `erc-open'
instead.
