I had to use the -o allow_other and -o default_permissions with sshfs to
get it to work properly with screen.  The symlink directory problem was
fixed by calling "screen -X setenv PWD /full/path/to/directory"  before
calling screen to open a new window.  I don't know why it is needed only
on symlink directories but it works.
