Since we're re-wording, "a special exception" doesn't seem quite right
to me. I'm not sure what rule being discussed it is an exception
to. Perhaps "in particular".

What about a seperate tag for #!/usr/bin/env ? The wording could be more
precise, and it does seem like the current tag conflates two (somewhat
related, but distinct) issues,

Yes, I realize my two suggestions are somewhat contradictory ;).
