It _should_ *always* matter. Did you delete the file or not? If it didn't
matter, why waste your time attempting the deletion?

Having delete-file return the value is: a) consistent with what I think
is the expectation of most CS folks; b) the most efficient, since it
already knows the exact point of any failure, and basically just passes
the return value it gets from the underlying OS.
