On the diff-callbacks3 branch, correct a few faults detected by
Julian Foad in his review of the first diff committed to this branch.

Review by: julianfoad

* subversion/include/svn_wc.h
  (svn_wc_diff_callbacks3_t): Edit comment to clarify the naming of
   state variables.

* subversion/libsvn_wc/diff.c
  (svn_wc_get_diff_editor2,
   svn_wc_diff4): initialize a baton with apr_palloc() because zeroing
   out the memory is not required.

* subversion/libsvn_client/merge.c
  (merge_dir_opened,
   merge_dir_closed): Remove the initialization of an unused variable.

* subversion/libsvn_client/diff.c
  (diff_dir_deleted): Restore statements that were unintentionally
   deleted by the original diff.
