[sftp-client.c]
     prefer POSIX-style file renaming over filexfer rename behaviour if the
     server supports the posix-rename@openssh.com extension.
     Note that the old (filexfer) behaviour would refuse to clobber an
     existing file. Users who depended on this should adjust their sftp(1)
     usage.
