Ah, I see what you're saying but I don't think that's plausible.

The point is that the only reason that 2.9.5 can possibly have for
referring to 2.14 at all, is that they want functions to behave just
like special built-in commands.   Otherwise there's no point referring
to that section at all.   If they wanted functions to behave like every other
command (which is what they should have wanted) they could have just said
nothing at all, and allowed the general rules for var assignments preceding
commands (which is not 2.14) to apply, or if they thought reinforcement was
needed, explicitly said that a var assignment on a func call works the
same way as on any other command (except special built-ins).

My guess is that they didn't do that, because that wasn't the way that ksh
worked (and still isn't the way that ksh works).
