It needs to be a bit more complicated than that, because you first
have to be sure that the braces are not already quoted and do not form
a valid comma-separated (or ".." range) brace expression.  Also,
should anything special happen if there is a valid brace expression
inside the invalid brace pair?   Is this single- or double-quote
equivalent, or something new?

As an aside to the latter, it might be nice if providing a
prefix-argument to quote-region caused it to use double instead of
single quotes.
