 > I am not convinced (not even a little). No exceptions to the standard
 map creation conventions unless it is absolutely fundamental to what the
 module does. If this was a edit-in-place module like r.null maybe I could
 buy the argument, but it isn't. Either deal with all of the input map's
 native bounds, or use the current region, not half and half. Using the
 current region settings gives the user the choice of which one they want.

 In theory I would agree, but not everybody knows that for a 3 arcsec SRTM
 g.region -a res=00:00:03 is wrong and only g.region align=SRTM properly
 aligns the region to the raster map.

 If you want to respect the current region, you would need to remove the
 align=input option from g.region in r.fullnulls when you zoom to the
 holes. You could zoom to the raster buffer instead which has been created
 using the current region.
