Supplies now go to some effort to enforce the supply grammar (emit*
[done|quit]); you have to go out of your way (like, actually ask for an
unsanitized supply) to get the previous behavior (which you may occasionally
want to do for performance reasons). Tests in S17-supply/basic.t. Note that
values emitted after a done will simply be dropped, so the grammar is followed
from an observers point of view.
