Since it's not just me who finds it really useful to set the shutdown
message (see http://lists.omnipotent.net/pipermail/lcdproc/2007-March/011540.html
), I figured I'd extract the relevant bit from
contrib/patches/lcdprocserverOPT.diff so it can get applied to the
main source tree.

Attached is a patch that adds a [server]goodbye key, which controls
the message displayed on the LCD when LCDd exits.  If the message is
longer than 16 or 20 characters (dependant on the size of your
screen), it will continue onto the second line.  As a bonus compared
to contrib/patches/lcdprocserverOPT.diff, if your message is less than
16/20 characters, the second line is blank instead of still displaying
the second line from the default message :)  It also adds some
documentation to LCDd.conf.

The patch is made against LCDproc 0.5.1.  If it gets accepted, I'll
send a followup patch to remove this part from lcdprocserverOPT.diff.

Thanks.

Peter.
