45 unsigned drop; /* code bits to drop for sub-table */
152 with length len. That code is converted to an index by dropping drop
153 bits off of the bottom. For codes where len is less than drop + curr,
154 those top drop + curr - len bits are incremented through all values to
160 new sub-table should be started. drop is zero when the root table is
161 being filled, and drop is root when sub-tables are being filled.
206 drop = 0; /* current bits to drop from code for index */
218 this.bits = (unsigned char)(len - drop);

294 len is equal to curr + drop, so there is no loop needed to increment
