[PD] IEM GUI blank "label" message causes weirdness

[David NG McCallum]

All,

If you send a "label" message to an IEM GUI without an argument it 
doesn't replace the label field in the patch file with "empty" (like it 
does if you manually clear the label in the GUI properties), but just a 
blank.

This causes all manner of weirdness by shifting all the GUI's arguments 
over by one.

I've seen this with the radio buttons and the sliders, I assume it's the 
same for the rest of them.

See the attached patch, open radiomain.pd and follow the instructions.

Cheers,
David

ps. Of course a "label empty" message behaves properly, but I don't 
think the blank "label" message ought to behave this way.
