Create '1.9.x-crop-safety' branch based of the '1.9.x-update-tc-detection'
branch.

This branch makes 'svn --set-depth X' keep your local changes, if there
were any in X. Before this it would keep them if 'X' was modified, but
not if only a descendant was.

* subversion/libsvn_wc/crop.c (1491756,1661580,1661585,1661589,1661591,1661682)
  (crop_children): Rename pool. Walk only BASE children. Only delete
    if the only change in the tree is a delete. Otherwise recurse
    on children with depth empty. Use svn_wc__db_base_remove() as
    we don't want to touch WORKING.
  (svn_wc_exclude): Check tree for changes before marking it excluded.
    Crop children if not allowed. Use svn_wc__db_base_remove() as
    we don't want to touch WORKING.
