It's awkward. How about having `read-language' (or a variant?) somehow
report where the specification after `#lang' or `#!' started?
Currently, `read-language' implicitly reports the end of the
specification by leaving the port position there; if it seems useful,
we could make that more explicit at the same time.

That's where I always end up, too. A somewhat more restrictive syntax
would work, but it wouldn't be especially simple. It's easiest to just
use the syntax that we already have, even if it's a bit Scheme-centric.
