patch 9.1.0430: getregionpos() doesn't handle one char selectionv9.1.0430

Problem:  getregionpos() doesn't handle one char selection.
Solution: Handle startspaces differently when is_oneChar is set.
          Also add a test for an exclusive charwise selection with
          multibyte chars (zeertzjq)
