HR preceeded by ***word*** doesn't render as HR

[kutetapolu]

Input:

***test***
***

Output (second line will be rendered as a literal ***):

<p><strong><em>test</em></strong>
***</p>

Expected output according to Markdown.pl:

<p><strong><em>test</em></strong>
</p>
<hr />

The same problem occurs with --- and ___ as HR.

I think it can be fixed by changing RE in HRProcessor:

497c497
<     RE = r'^[ ]{0,3}((-+[ ]{0,2}){3,}|(_+[ ]{0,2}){3,}|(\*+[ ]{0,2}){3,})[ ]*'
---
>     RE = r'^[ ]{0,3}((-+[ ]{0,2}){3,}|(_+[ ]{0,2}){3,}|(\*+[ ]{0,2}){3,})[ ]*$'

Here's what Babelmark shows. Looks like a bug.
