Well, I partially agree with you in that point. However, I still
believe ISBlockGetSize is a bit confussing. Perhaps we can condensare
ISBlockGetSize() and ISBlockGetIndices() in a single call like this:

PetscErrorCode ISBlockGetInfo(IS is, PetscInt *n, const PetscInt *idx[])

Getting the actual, 'unmapped' block indices is a rather special call.
