[PATCH 1/2] builtin-commit: fix summary output.

[Junio C Hamano <gitster@pobox.com>]

Because print_summary() forgot to call diff_setup_done() after futzing with
diff output options, it failed to activate recursive diff, which resulted in
an incorrect summary.

 * This fixes the "5 files" problem you saw with your commit, which was
   totally bogus (it looked at "git diff-tree HEAD" output that was
   non-recursive, discarding the change of tree t/ itself).  Now it will
   show "7 files" in line with your "git show".
