Agree, but I think it matters that .ONESHELL behave like other special
targets. Principle of least surprise, etc. Cf the .NOTPARALLEL target
which is documented as

   "If .NOTPARALLEL is mentioned as a target, then this invocation of
make will be run serially ..."

There's nothing said to the effect that it applies only to rules
defined after the line on which it appears. But this is the kind of
detail on which I'd await an opinion from Paul. I always put my
special targets at the top so I have no idea how they'd behave
elsewhere.
