I think so, but Eric has the last word on this.  The results should come
after the call, but the current implementation would look for the
results line from the beginning of the buffer.

I can't see how it would be much more difficult to have a #+CALL where
you want the result (independently of where the source block is), but it
seems pretty limiting to allow only a single result.

I didn't get what you were trying to do there, but it's pretty obvious
now.

Anyway, more testing shows my patch will prefer the results line after
the call, but if you then insert another call before that (without an
existing result) the result from the now second call will still be
clobbered, so there needs to be some more fixing by limiting the search
to not extend across other calls or source blocks.  Or this really is a
feature, although I don't really see much use for it.
