I only discovered that they existed when I compared the XML and Tcl/Tk
code in response to this thread. The fact that --script actually
outputs them is an artifact of simply dumping every field of
"struct Option".

Note that G_parser() splits the ->descriptions field into individual
entries and stores the result in the ->descs field. The --help, XML
and HTML output all use that field. The Tcl/Tk code doesn't, though.
