Removing assertion that degree-1 blocks don't have a supporting homology
Removing assertion that degree-1 blocks don't have a supporting homology

Strictly speaking this isn't true (a block could conceivably have been
created by pinching itself together). And the assertion
really doesn't matter, since the "number of possible supporting
homologies" isn't a hard-and-fast upper bound because of things like
overlapping blast chunks.
