As Joe Buck pointed out, we *do* warn about the use of the
uninitialized variable when writing `int a = a;'.  I'm pretty sure we
didn't before, but now we do.  So, the whole point with which I
regretfully started this debate is moot.  Looks like another case of a
warning that should only be emitted in the presence of the flags
`-flame -War'.  Apparently, I've become an expert in generating those
:-/
