	* src/functions/fn-lookup.c (gnumeric_indirect) : This solution is
	  more paletable.  Always attempt to add the dependency, but only
	  actually do so if the calling cell does not already depend on the
	  indirected cell.

	* src/eval.c (cell_add_explicit_dependency) : Expand this function to
	  test to see if a dependency already exists.
