[PATCH] stdio: fix vfscanf with matches longer than INT_MAX (bug 27650)

[Florian Weimer]

* Alyssa Ross:

> Patterns like %*[ can safely be used to match a great many characters,
> and it's quite realisitic to use them for more than INT_MAX characters
> from an IO stream.
>
> With the previous approach, after INT_MAX characters (v)fscanf would
> return successfully, indicating an end to the match, even though there
> wasn't one.

I've pushed to this commit, thanks.

We can integrate the test once your copyright assignment is on file.

Thanks,
