  * in the correct multiple to subtract, we can shift a byte at a time.
  * This produces a 40-bit (rather than a 33-bit) intermediate remainder,
  * but again the multiple of the polynomial to subtract depends only on
- * the high bits, the high 8 bits in this case.  
+ * the high bits, the high 8 bits in this case.

  * The multiple we need in that case is the low 32 bits of a 40-bit
