Comment:

 Yes, I realise this. However, there's a simple solution, albeit it changes
 the interface. The solution is for transform_width to take a pair of
 iterators (begin and end), not one, so that it knows exactly when to stop
 and not go over the end.

 I have seen a lot of people using transform_width for base64 encoding with
 std::copy, which with current implementation is what one should not do.
 Well, it should either not compile at all or should work as expected (in
 the most intuitive way)

 Thanks for a quick response by the way
