Remote directory on sftp logon is set to user's home directory #7

Fix the reported problem #7. Remote directory set to remote user's home
directory like its is done on openssh on all platforms. Users can then
cd to "Documents" directory. Actual fix was to expand "." to user's home
directory so that pwd showed it correctly rather than just showing a
dot.
