Hi,
When getting an empty file while using CURLOPT_WRITEFUNCTION option,
there is no call of write function because it is stopped in line 293 in
lib/transfer.c:

       /* if we receive 0 or less here, the server closed the connection
and
           we bail out from this! */
        else if (0 >= nread) {
          k->keepon &= ~KEEP_READ;
          FD_ZERO(&k->rkeepfd);
          readdone = TRUE;
          break;
        }

In this case the empty file does not created in client host.
When 0 bytes received, the case should distinguish between the first
time and others, so for the first time the write function should be
called with 0 bytes just to create an empty file.

What do you think?
