  * Description:
- *   Reduce the size of the chunk specified by the node
- *   structure to the specified size.  this internal logic
- *   is used both from memalign to dispose of any trailing
- *   memory in the aligned allocation and also by realloc
- *   when there is a request to reduce the size of an allocation.
+ *   Reduce the size of the chunk specified by the node structure to the
+ *   specified size.  this internal logic is used both from memalign to
+ *   dispose of any trailing memory in the aligned allocation and also by
+ *   realloc when there is a request to reduce the size of an allocation.
  *
  *   NOTES:
  *     (1) size is the whole chunk size (payload and header)
  *     (2) the caller must hold the MM semaphore.
