Y'all and No?

Douglas Bigham:

> Does anyone know if, in the 'lects where this is 2nd person plural, has "y'all" has taken on a more polite meaning than "you"?

That has been suggested, but I'm not yet convinced of it.  The only times
I ever hear "y'all" used to a single person are institutional or
associative uses -- which are perhaps related to politeness, of course.
