Good catch! Here is a patch which fixes this issue too.

> (1) stop calling the user-defined functions and behave similarly to most other built-in types;

This is done in 3.x.

> (2) stop trying to mutate that poor string in-place and always just create a new one.

The patch can be simplified by removing 6 lines. But this will slow down integer formatting by few (about 2-7) percents in worst case. Not a big deal.
