Agreed, it's redundant. encrypted_control() currently strips off the
"encrypted change-master-key" string and then calls datablob_parse(),
which still expects a key_cmd (eg. new, load, or update).  Instead, we
could pass "change-master-key" to datablob_parse() as the key_cmd and
make the necessary changes.

thanks,

Mimi
