Between versions 1.44 and 1.45 the timestamp had gotten lost on the
backed up course URL. Even though this looks ugly, for data recovery,
all previous versions and the timestamp are important. People should
not get into the habit of changing course URLs anyway. The new "uploaded"
coursedocs-based mechanism should make changing welcome pages, etc, easier,
anyway.
