Comment (by Petr Dlouhý):
@Mariusz Felisiak You cannot achieve the intended behaviour by that
`Concat`, because
a) I wanted to sort the number in reverse order
b) The length and content of the concatenated strings can vary.
I spend quite some time figuring up that concatenate function, until
finally I gave up.
So I think, this is valid use case for feature request, because the
concatenation is either not possible at all, or it would be quite complex
and very unreadable code.
I looked at the `ChangeList.get_ordering()` function, and since it returns
ordering list it might be quite simple code.
