fix silly next/rules.md modification

It turned out that `next/rules.md` was modified in the section marked
between:

```html
<!-- START: this line starts content from: inc/rules.closed.hdr -->
```

and:

```html
<!-- END: the next line ends content from: inc/rules.closed.hdr -->
```

Instead, `inc/{guidelines,rules}.*.hdr` should be modified as
 `make gen_status` uses these files to form this content.

inc/rules.pending.hdr
