1st this question is probably better for the GRASS mailing list.

QGIS & GRASS ship compiled binaries of c code, if you want to see the
source you have to download the source:
http://grass.osgeo.org/download/software/sources/

Specifically you can browse to the algorithm you want and just pull that
file:
http://svn.osgeo.org/grass/grass/branches/releasebranch_6_4/raster/r.horizon/

Enjoy,
