a bug with src element extending

[Olorin <Vivliofika yandex ru>]

<code>
<img src=/img/img.bmp>
</code>

doesn't work because of extention error. The first "/" should be extended here to "protocol://domain:port/"



But

<code>
<img src=img/img.bmp>
</code>

works. And it extends to a relative path.



Thank you.
Olorin.
