  40    If DEPTH is svn_depth_empty, revert just the properties on the
  41    directory; else if svn_depth_files, revert the properties and any
  42    files immediately under the directory; else if
  43    svn_depth_immediates, revert all of the preceding plus properties
  44    on immediate subdirectories; else if svn_depth_infinity, revert
  45    path and everything under it fully recursively.
  46
  47    CHANGELISTS is an array of const char * changelist names, used as a
  48    restrictive filter on items reverted; that is, don't revert any
  49    item unless it's a member of one of those changelists.  If
  50    CHANGELISTS is empty (or altogether NULL), no changelist filtering occurs.
  51
  52    Consult CTX to determine whether or not to revert timestamp to the
  53    time of last commit ('use-commit-times = yes').  Use POOL for
  54    temporary allocation.
  55
  56    If PATH is unversioned, return SVN_ERR_UNVERSIONED_RESOURCE. */
