As far as I can see using cflow (an old but trusted utility for printing a 
graph of a function's call hierarchy) G_get_null_value_row() does not call 
G_get_cellhd(), nor do any of the functions called by it all the way 
through its call hierarchy.

Although this isn't relevant here, Markus did ask me to remind him about 
cflow, which, since it comes from the same era as much of the code (at 
least in libes/gis), does show what is calling what, or what is called by 
what if inverted.
