Outstanding Use of svn_wc__node_walk_children()
===============================================

These are known consumers of svn_wc__node_walk_children(), which we'd
ideally like to eliminate altogether from the codebase in favor of
less ... one-at-a-time approaches.

---

subversion/libsvn_client/changelist.c

   svn_client_add_to_changelist() - Apply a changelist to a tree (up
     to specified depth), on file nodes only, and possibly only those
     matching one of a specified set of changelists.  Needs to notify
     per-path, and differently based on whether the file has a
     pre-existing changelist association or is a directory (skipped),
     etc.

   svn_client_remove_from_changelists() - Clear changelist assignments
     from a tree (up to specified depth), possibly only for nodes
     matching one of a specified set of changelists.  Needs to notify
     per-path for those files (only) from which changelist
     associations were removed.

   svn_client_get_changelists() - Drive callback to report all
     changelist associations in a tree up to a specified depth.

subversion/libsvn_client/info.c

   crawl_entries() - Crawl a tree (up to specified depth) driving an
     svn_info_receiver_t callback.  The current implementation not
     only uses the svn_wc__node_walk_children() interface, but the
     callback it drives peeks back into the WC database many, many
     times per node.

subversion/libsvn_client/prop_commands.c

   set_props_cb() - Crawl a tree (up to specified depth) setting a
     property name/value pair on each item therein (possibly restricted
     to those which match one of a specified set of changelists).
     Needs to notify on a per-path basis.
