I don't mind.

I don't think it is. mbsnrtowcs is supposed to reset the the state (just
like mbsrtowcs does) when it reaches the end of input.

In that case, mbsrtowcs would be just as broken?

I am not really attached to my patch, but I do want to remind you that
mbsrtowcs and mbsnrtowcs (just like wcsrtombs/wcsnrtombs) should be
equivalent as long as the input is completely processed. I don't think
nozaki-san's version provides that.
