Argh!  How annoying (for a couple of reasons).  I managed to not know
that, overlook wherever K&C said it was the case, and not word my eqn(1)
revisions so as to capture it.

I think in pedagogial examples, we should train eqn writers to always
quote braces they mean to use as symbols, even in context where the
grammar makes it unnecessary.  I find this semantic rule, where braces
get de-powered by a preceding primitive, perverse.

Guess I'll be pushing another eqn man page change.  Thanks for bringing
it to my attention.
