- Switch from echo to printf for all translations: This is more

  stable than having expansions in messages that might change
  independent of the message.
- Add print_patch function and always use it when printing patch
  names. Remove -n options from various scripts and use a global
  switch QUILT_PATCHES_PREFIX in .quiltrc to decide between patch
  names with and without directory prefix. Depending on user
  experience this switch may eventually go away.
- Add --diffstat option to refresh command: If given, this option
  inserts diffstat statistics at the end of the patch header, or
  refreshes the existing diffstat output. No special tags in the
  path file (%diffstat or the like) are needed.
- Minor fix inserting changelog into RPM specfile.
