LFTP 3.5.13 patch

[Craig Ruff]

When performing a data transfer, the server can send either a 125 or 150
response to indicate the transfer is starting.  RFC 959 states in section
4.2 (FTP REPLIES) htat "The server-FTP process may send at most, one 1yz
reply per command.".  Since the server has a choice of 125 or 150, lftp
needs to accept either to indicate that the data transfer is starting.
Attached is a small patch to 3.5.13 that appears to work correctly.
