The established way we do this is not to have -latest pointer, I
would think, and instead, make -latest be the actual thing.  That is
how $GIT_DIR/index is updated, for example, by first writing into a
temporary file and then moving it to the final destination.  Is
there a reason why the same pattern cannot be used?
