ah, right - between prerequisites at a given depth, second-expansion now
happens in the same order as execution of their rules, fair enough. I
was thinking of the fact that, if you'd started with
all: $$(info 2nd expansion for all) hello.tsk bye.tsk; echo built both
then its info would appear first, although its rule would be run last.
I suppose that's unchanged by this patch, though,
