Comment (by Tritlo):
I've reworked the substitution suggestions a lot over the past few weeks,
and I've updated the sorting to be based on sizes of matches rather than
by subsumption (though sorting by subsumption is still available via a
flag). I hope to submit the patch this weekend, after I've updated the
documentation.
