     [sftp-batch.sh sftp-badcmds.sh sftp.sh sftp-cmds.sh sftp-glob.sh]
     date: 2009/08/13 01:11:19;  author: djm;  state: Exp;  lines: +10 -7
     Swizzle options: "-P sftp_server_path" moves to "-D sftp_server_path",
     add "-P port" to match scp(1). Fortunately, the -P option is only really
     used by our regression scripts.
     part of larger patch from carlosvsilvapt@gmail.com for his Google Summer
     of Code work; ok deraadt markus
