- backport upstream commit r1528718 into mod_dav [1].

  This is needed because of a bug [2] due to an incorrect
  implementation of RFC 4918.
  The symptoms are a failure to copy a svn tree via DAV:

- fix package installation with old pkg tools (create empty
  folders in pkg-plist even staging is enabled)
