- Document the -H option and 'H' key alongside other options and keys

  rather than at the bottom of the manpage.
- Remove an obsolete comment about SWAIT being a stale state.  It was
  resurrected for a different purpose in FreeBSD 5 to mark idle ithreads.
- Add a comment documenting that the SLEEP and LOCK states typically
  display the name of the event being waited on with lock names being
  prefixed with an asterisk and sleep event names not having a prefix.

-The \*(lqABANDONED\*(rq state (known in the kernel as \*(lqSWAIT\*(rq) was
-abandoned, thus the name.  A process should never end up in this state.
+If a process is in the \*(lqSLEEP\*(rq or \*(lqLOCK\*(rq state,
+the state column will report the name of the event or lock on which the
+process is waiting.
+Lock names are prefixed with an asterisk \*(lq*\*(rq while sleep events
+are not.
