Ok, all the changes here are just to reduce the size of string
used from an unstring to an nstring. Unfortunately this cannot
be correct as it would cause truncation for multibyte characters
in code pages like Japanese.

It may be that the change you added causes extra non-zero bytes not
to be examined in the comparison functions. If that is the case
the following patch should have the same effect. If you could test
this instead of your patch I'd appreciate it.
