SUDO file copies do not correctly handle target paths with trailing file separator

[vpartington]

If you copy a directory to a host connected by way of SSH/SUDO to a location called /tmp/foo/, you would expect the contents of the directory to appear in the /tmp/foo directory but the actually appear in a directory called /tmp/foo/hostsession.tmp.

This problem does not occur when the target directory is specified without a training slash, i.e. /tmp/foo.
