None whatsoever. The person responsible should be keelhauled.
Oh, right... Sorry.

It's just a remnant of a refactoring. I started out working on
lists on the form [S div 1000, ..., S rem 10], but realized that
I could just use the lists of character codes instead. But I
didn't tidy up after changing to integer_to_list(S). Improved
version attached.
