[PATCH 0/4] HMM tests and minor fixes
These changes are based on Jason's latest hmm branch.
Patch 1 was previously posted here [1] but was dropped from the orginal
series. Hopefully, the tests will reduce concerns about edge conditions.
I'm sure more tests could be usefully added but I thought this was a good
starting point.
