PHP_INI_MH()'s new_value_length being non-zero for NULL new_value?

Hi all, I realized that setting default_charset does not set *.internal_encoding/etc. So I looked into what's wrong and found PHP_INI_MH()'s new_value_length being non-zero for NULL new_value. This makes fail to set proper value for *.intermal_encoding/etc. This happens from PHP 5.6 branch. It was 0 for null value otherwise encoding setting was not working from the beginning. Is this change intended or a bug? Or I got zero length during patch development by accident? If this behavior wouldn't be changed, I'll just commit patch that fix the encoding INI issue.
