- /* Like in other compression formats such as LZX and DEFLATE, match
- * offsets in LZMS are represented as a position slot, which corresponds
- * to a fixed lesser or equal match offset, followed by a
- * position-slot-dependent number of extra bits that gives an additional
- * offset from that position slot. Because the full number of position
- * slots may exceed the length of the compressed block, here we
- * calculate the number of position slots that will actually be used in
- * the compressed representation. */
