Is assumed length char also supposed to hit TODO? If so, could you please add this test as well:
```
subroutine test_elemental_char_min_assumed_optional(a, b, c, res)
  character(*), intent(in) :: a(:), b(:)
  character(*), intent(in), optional :: c(:)
  character(*), intent(out) :: res(:)
  res = min(a, b, c)
end subroutine
```
