(it is about v.out.pov):
http://grass.osgeo.org/grass64/manuals/html64_user/v.out.pov.html

I think that the empty ("") answers in
grass64/vector/v.out.pov/main.c

    58      zmod_opt = G_define_option();
    59      zmod_opt->key = "zmod";
    60      zmod_opt->type = TYPE_STRING;
    61      zmod_opt->required = NO;
    62      zmod_opt->answer = "";
    63      zmod_opt->description =
    64          "Modifier for z coordinates, this string is appended
to each z coordinate.\n"
    65          "\t\tExamples: '*10', '+1000', '*10+100', '*exaggeration'";

    66      objmod_opt = G_define_option();
    67      objmod_opt->key = "objmod";
    68      objmod_opt->type = TYPE_STRING;
    69      objmod_opt->required = NO;
    70      objmod_opt->answer = "";
    71      objmod_opt->description =
    72          "Object modifier (OBJECT_MODIFIER in POV-Ray documentation).\n"
    73          "\t\tExample: \"pigment { color red 0 green 1 blue 0 }\"";

should be removed.
