I took this to -workers and a patch has been posted.  A change in
tokenization logic accidentally broke lookup of conditionals where
there's a dash inside the conditional name.

No idea whether my patch or something else will be applied, but know
that what we have includes a regression test so that this one won't slip
through again.

That workaround applies still.  And now we know why it works.  :)
