      7  * To distinguish bit positions from the description text, they should use
      8  * octal or hex escape sequences.  Of these, octal escape sequences are less
      9  * error-prone, as they consist of at most 3 octal digits, whereas hex escape
     10  * sequences consume as many digits as available.
