patchbomb: let diffstat prompt only once with complete summary

This changes the behaviour of --diffstat.
Before the user was asked for confirmation of each patch with its
description and diffstat, and a final summary.

Now there is only one prompt right before sending with a final
summary which does not include the patch descriptions, but the
message details and the diffstats:

  Final summary:

  From: sender
  To: recipient(s)
  Cc: (if present)
  Bcc: (if present)
  Reply-To: (if present)
  Subject: [patch 0 of x [flags]] intro (if present)
      a |  28 ++++++++++++++++++++++++++++
      b |  15 +++++++++++++++
  Subject: [patch 1 of x [flags]] subject
      a |  28 ++++++++++++++++++++++++++++
  [ ... ]

  are you sure you want to send (yn)?
