This (documentation) should be implemented into the parser.
A way could be to check if a module used

cd ~/grass61/lib/gis > grep OUTPUT parser.c
        case G_OPT_R_OUTPUT:
        case G_OPT_V_OUTPUT:

If so, a first flag should be predefined with --o and explanation,
the rest follows as usual. This will give us motivation to then
update to G_OPT_R_OUTPUT and G_OPT_V_OUTPUT everywhere, such as

        parm.output = G_define_standard_option(G_OPT_R_OUTPUT);

or
        parm.output = G_define_standard_option(G_OPT_V_OUTPUT);

Second advantage of using these definitions is that the description
is identical and already translated to all supported languages.

Only, I don't know how to make this suggestion possible...
