Right.  I think what Peter is actually suggesting is that BIT VARYING
(which must be special-cased in gram.y) could be equivalent to
"bit varying" (as a quoted identifier, that works already in most
places, and arguably should work everywhere).  There's a certain amount
of intellectual cleanliness in that.  OTOH, it's not apparent that it's
really any *better* than `varbit' or your choice of other space-free
internal names.

If SQL92 were a moving target then I'd be concerned about having to
track the special cases in a lot of bits of code ... but it's not
a moving target.
