The -d option of scp, as for the -t option, is an undocumented one, and is used for specifying that we are working in directory mode. In effect, this flag ensures that the target is to be a directory, and implies that scp will check that the target directory exists before attempting to copy the contents of the source. Adding this flag to the scp sink makes the communicator behave correctly in relation to the scp command as it would be used by clients, rejecting copies to a non-existent destination directory, rather than mistakenly creating it, partially (or completely) copying the source's contents, and potentially succeeding where it should not.
As with the directory upload, not specifying the -d option in scp when uploading a file may result in uploading succeeding even when the destination directory (if suffixed by a `/') succeeds, and makes the resulting file upload take the name of the destination directory. To avoid this problem, we add the option so that if the destination is explicitely a directory, this does not succeed anymore.
