Changes (by nickm):

  * status:  needs_review => needs_revision


Comment:

 Looks good.  A few things to fix up or add on review:

   * changes files should mention bug numbers
   * The hex-number-formatting function should probably get extracted and
 get a couple of unit tests of its own.
   * We still write our if (...)s without internal spaces inside the
 parenthesis.
   * Does this break badly if sizeof(int) > 4, and we ever get a huge
 errno?  If so we should check for values more or less than INT32_MIN and
 INT32_MAX.

 Up to you if you want to fix these or if you'd rather I do it.
