This just lets one circumvent *.info, but the application would be
obliged to learn about block sizes through some other channel.  The
problem here is that PetscOptionsInsertFile dumps those options
(unprefixed) into the global namespace, and that is (unless I'm
mistaken) the only way for the block size to be delivered to the vector.
I think this is actually difficult to resolve in a completely
satisfactory way, but perhaps I'm missing something.
