 I hadn't seen that one (there were a lot of changes in #171 a couple of 
 years ago, mostly good but a few bugs).  A quick check shows 21 places in 
 the state table that can get there, including the default ansi_table. 
 That one looks like an error; the others I'll have to sift through and 
 check for other possible errors).  The
 
              if (!string_used)
                  break;
 
 does guard against most errors.
 
 Resetting the state to ground at the beginning does ensure that the check 
 if there's no string_used doesn't prevent the state from resetting 
 (agree).
