One caveat: --overwrite is only listed as an available flag for
modules which have at least one option with "new" in the gisprompt
field or which explicitly set the "overwrite" field in the GModule
structure (there's no equivalent for scripts).

All modules accept --overwrite, regardless of whether it's listed. If
there are no "new" options, the parser doesn't perform overwrite
checks, but it will still set GRASS_OVERWRITE=1.
