Replace the fuzz test with one that enumerates all relevant patterns
up to a certain length.
For conflict detection, we don't need to check every possible method,
host and segment, only a few that cover all the possibilities. There
are only 2400 distinct patterns in the corpus we generate, and the
test generates, indexes and compares them all in about a quarter of a
second.
