[GRASS5] shade.rel.sh bug?

the shade.rel.sh script does IMHO not work properly any more.
If i create a shaded relief in plain areas (even surfaces/no slope)
there are NULL-holes in the raster. My DEM has no NULL-values. 
I think that this comes from different handling of division by zero?

This has maybe a very simple solution (if-clause in the mapcalc
function?), but i don't know which. 
I'll report this to the RT if i get no feedback for a solution.

Just removed my grass4.3 setup, so that i can no longer test.
