 Modified Files:
        src/share/man/man3: rbtree.3
 
 Log Message:
 Fix documentation of rbtree(3) iteration.
 
 . Fix sense of rb_tree_iterate(rbt, NULL, ...).
 . Document RB_TREE_MIN/RB_TREE_MAX to avoid relying on that sense.
 . Document RB_TREE_FOREACH and RB_TREE_FOREACH_REVERSE to simplify
 iteration.
 
 Addresses PR lib/46034 and PR lib/47144.  It would have been nice to
 make `x = NULL; while ((x = rb_tree_iterate(t, NULL, ...)) != NULL)'
 DTRT to traverse t, but it's too much late for that now.
 
 We probably ought to have an RB_TREE_FOREACH{,_REVERSE}_SAFE too.
 
 ok christos
