Do you mean that (the currently documented):

"If from and to have different lengths, the extra characters in the 
longer of the two are ignored. The length of str will be the same as the 
return value's."

would then change into:

"If from and to have different lengths, the extra characters in the 
longer of the two are assumed to be the empty string, thus 
removing those characters. The length of str will be the same as 
the return value's unless the from and to have a different length."
