	* src/eval.[ch] (cell_add_explicit_dependency) : New function.

	* src/functions/fn-lookup.c (gnumeric_indirect) : Clear all
	  dependencies the calling cell has and regenerate them anytime the
	  function is called.  This is somewhat wasteful but is IMO a better
	  space time trade off than penalizing all depends to be able to flag
	  which dep is an indirection dep.

	  This method will cause problems if multiple indirection calls are
	  used in a single expression.
