This is the small code fix which is needed for the new options.xml file.
It is needed because otherwise the "--prop:name=value" is showed
incorrectly.

There is another problem though, when compiling with --without-logging
the help message isn't displayed at all! We *must* change that somehow.

Curt: good point, the SG_LOG()'s have been switched to cout's ...
