I think we should fall in line with GNU behaviour here.
If you really think you need to do this:
you can already do this:
which does the same thing and is more explicit about which character is repeated to fill set2.
(Although generally, I think that if you are at that point you are already using the wrong tool).
However, I do not have strong opinions on this and would happily implement this the other way if someone is clearly in favour of that.
