 a wrapper.

 OK, nice.

 > r42183 had two parts: fixing the GUI menu, and cosmetic changes to
 r.mapcalc. The latter included renaming the input= option to file=, but
 overlooked the fact that it synthesises "input=-" when run without
 arguments (to preserve the historical behaviour). The change broke this
 behaviour; r42210 reinstates it.

 Why not just

 against r42182? AFAICT, no modifications needed for raster/r.mapcalc

 BTW, could the Map calculator get an output window and the r.mapcalc
