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,})[ ]*$'
