But that table doesn't really answer the question, does it? For both "G_OPT_R_INPUT" and "G_OPT_R_MAP" it lists "old input raster map". AFAIU, "G_OPT_R_MAP" is for modules that use only one input raster map. In those cases, the corresponding input option should be named "map=". "G_OPT_R_INPUT" would then be for modules that have either several raster map inputs or raster and vector maps as inputs. The corresponding input options would then be called "raster=" and "vector=" in case of exactly one raster and one vector input map. Further special cases are covered by "G_OPT_R_BASE", "G_OPT_R_ELEV", etc.: They all exist for semantical purposes. All of them stand for raster input maps.
