+ Fix SF/1795259
+ * aggcat.spad.pamphlet (HomogeneousAggregate): Make
+ CoercibleTo(OutputForm) if argument is of that category.
+ (BinaryRecursiveAggregate): Weaken condition for coercion to
+ OutputForm.
+ (OneDimensionalArrayAggregate): Likewise.
+ (Tuple): Likewise.
+ (IndexedList): Likewise.
+ * tree.spad.pamphlet: Likewise.

* Makefile.pamphlet (INTERPSYS): Now take system root directory
