catarrh 855c9f40b1 v3.28.5: the batch panel's Stop wording (RU)
The panel's hint read "«Остановить» завершает текущую карту" - a poor
translation of "Stop finishes the current card first".  It is now
"«Остановить» завершает работу после окончания обработки карты", and the
help row's phrase is aligned ("...после окончания обработки текущей
карты").  The EN text is unchanged.
