It looks like the reason is that resize_string_data doesn't update the string 
byte and character counts in the branch where it decides that no reallocation 
is required.  So we get a string with correct data, but incorrect size 
attributes.

I'd also add an assertion there that the string is a multibyte one, since the 
code implicitly depends on that.
