None of these, or any of GRASS's other surface interpolation tools that I'm
aware of, consider breaklines. Although a feature request was filed 4 years
ago: http://trac.osgeo.org/grass/ticket/793

You could probably generate hydro flattened surfaces separately and combine
them with the DEM manually using the raster calculator, but unfortunately I
don't think there is a one click button.
