> Pretty sure this was just a typo, but the SFTP spec, draft 13, specifies
> in section 8.2.1 that "The server MUST not respond with more data than
> is specified by the 'length' parameter".  We were always responding with
> 0-32k's worth of data, but (at least) the Mac transmit client was asking
> for only 16k chunks.  This confused it, as I believe it got the length
> via stat, and then would get an early (from its point of view EOF).
> Instead of closing the file and moving on, it would hang the transfer.
> (see attached patch)
