[Erc-help] erc-track XEmacs fixes in ERC 5.0.3

[Michael O. <mw...@gn...>]

In the process of testing ERC 5.0.3 before release, I found that a few
error messages showed up if you run /QUIT when channel buffers with
new content exist.  I tried to fix this by slightly modifying the
`erc-modified-channels-display' function in erc-track.el.

Another change I made was to add `erc-modified-channels-update' to
erc-disconnected-hook with the goal of wiping the track indicators
From=20the mode line when ERC quits, since sometimes the server buffer
indicators stay on the mode line after closing.  You might have to
have `erc-kill-server-buffer-on-quit' set to non-nil in order to
replicate this.  It doesn't seem to do the job though, so I'm going to
revert this change.

Both of these patches are included in the 5.0.3 release, and I've
migrated all the 5.0 release branch fixes into CVS head.
