Title: Fixing diff-comments and close by empty diff

Fixing bug for diff-comments by html formatter:
it was:
```html
-- /tmp/diffy20130605-4371-kywx0v-0 2013-06-05 13:58:53.000000000 +0200

++ /tmp/diffy20130605-4371-1arvip-0 2013-06-05 13:58:53.000000000 +0200

```
adding row to close

directly if the diff is empty -> allow-empty-diff. Better xhtml and better for parsing.
