Huh, even now I don't think this is quite what the original patch intended.

"EXAMPLE" is defined as a command in doc.str, but there are no existing 
uses of it.

It's different to e.g. DESCRIPTION, RETURNS, PORTABILITY etc. in that it 
doesn't emit a subheading "EXAMPLE", which I imagine is what was 
expected here.

(If you look at the currently generated info page for wcwidth, this 
example is part of the "RETURNS" subsection at the moment, which doesn't 
seem right.)

I'll send another patch.
