Yes, that would be nice, and it could be made to work. Most callers of
any "walk_entries" function don't want to see hidden nodes. (Just 2 of
the approx. 13 callers of svn_wc_walk_entries3() set "show_hidden =

I had a go the other day at rewriting this "walk_entries" interface to
include all the options as bitwise flags in a single 'options' argument.
See the attached patch. Calls would look like:

  return svn_wc_walk_entries4(path, parent_access,
                              &walk_callbacks, &walk_baton, depth,
                              cancel_func, cancel_baton, pool);


  return svn_wc_walk_entries4(path, parent_access,
                              &walk_callbacks, &walk_baton, depth,
                              | SVN_WC_WALK_ENTRIES_WITH_HIDDEN,
                              cancel_func, cancel_baton, pool);
