Underscore or asterisk at the end of a link renders as <em>

[nloveladyallen]

Input:

[foo_](http://example.com/bar_)
[foo*](http://example.com/bar*)

Expected output:

<p><a href="http://example.com/bar_">foo_</a></p>
<p><a href="http://example.com/bar*">foo*</a></p>

foo_ foo*

Real output:

 <p>[foo<em>](http://example.com/bar</em>)</p>
 <p>[foo<em>](http://example.com/bar</em>)</p>

foo_ foo_

I'm working on MMD 6 -- this is an entirely new, from scratch, rewrite designed to dramatically improve performance. One of the motivations was to come up with an accurate emph/strong parser that also improves performance.

For now, you can escape characters so that this doesn't happen, e.g. [foo\_].
