[PATCH] fix repos-to-wc copy dst parents creation

[[[
Correctly handle existing parent directories when performing repos-to-wc copy.

* subversion/libsvn_client/copy.c
  (repos_to_wc_copy): If add_parents flag is set and destination parent
  directory exists, but is unversioned, put it under version control. Wc-to-wc
  copy behaves this way, and so should repos-to-wc copy do.
