vim-patch:9.1.0446: getregionpos() inconsistent for partly-selected multibyte char (#29032)

Browse Source 
Problem:  getregionpos() behaves inconsistently for a partly-selected
          multibyte char.
Solution: Always use column of the first byte for a partly-selected
          multibyte char (zeertzjq).
