Description

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.
