Robin, I've just committed a slightly modified version of your patch to
svn, thanks it looks pretty cool :-). Can you please give it a try to
make sure I didn't break any thing.
The only changes I made where to fix the issue when changing the 'Big
Clock' setting didn't do anything until mythlcdserver was restarted and
gave the colon a bit of extra space around it. Most of the other changes
are just cosmetic.
My development box has a 4 line display but my production box has a 2
line Samsung VFD based on the hd47780 so I would be interested in your
patch to lcdproc. Could you email it to me thanks. I probably wont be
touching it until after the world cup though :-)
