patch 9.1.1479: regression when displaying localized percentage position

Problem:  regression when displaying localized percentage position
          (after v9.1.1291)
Solution: calculate percentage first (Emir SARI)

Cleanups made in ec032de broke the Turkish percent display, failing to
prepend it properly in cases between 0 and 10. In Turkish, the percent
sign is prepended to the number, so it was displaying it as `% 5`
(should have been `%5`), while displaying numbers bigger than 9 properly.
