Yes that's wrong.
However, the bigger problem is that dmcrypt's algorithm specification
does not allow all algorithms to be specified. In particular, algorithms
with dashes in their names cannot be represented in an unambiguous way.
The separation of chain modes and algorithm names is in fact unnecessary
and only complicates matters.
For now it's no big deal since the algorithms people actually use
can be represented. But it would be nice to get this fixed.

Looks good to me.
