I18N: Annotate indentation of the transaction summary

Translators are recommend to align the messages to prevent from
a broken table:

    Podsumowanie transakcji:
     Instalowanie:         6 pakietów
     Aktualizowanie:         33 pakietów
     Zastępowanie:         48 pakietów
     Usuwanie:         199 pakietów

(Last arguments moved to a new line to follow new clang-format.)
