Dear Max,

one can put fix and testcase into the same commit, if you decide to
split it up then first commit the testcase with an expected failure
and then when you fix things, fix the test result. This will show/track
the change in behavior.


In my initial review I had asked for a stronger post condition and I
still think this applies to the test. I see we have one truncation
test but I don't see a test that checks how many bits have been taken
from the hexstring.
