Presumably that should be G_define_standard_option()?

I can't see any use for that. In practice, you would probably end up
manually overriding as many settings as if you had just used
G_define_option(). E.g. I doubt that either the ->key or ->description
fields would be left untouched.

Also, the ->gisprompt setting is completely bogus; the string is never
localised, and neither "value" nor "parameter" are valid keys.
