<em> inserted incorrectly inside a hyperlink

Hi, actually I found the problem by converting my notes into markdown format.

I have a snippet like this

[Stochastic_Processes_-_1.4_analysis](Stochastic_Processes_-_1.4_analysis)

or for simplicity

[A-_B](A_-B)

Feed it to kramdown I got the following

$ echo "[A-_B](A_-B)" | kramdown
<p>[A-<em>B](A</em>-B)</p>

which should be <p><a href="A_-B">A-_B</a></p>.

I tried all the four, only the last one yields this problem:

• [A_-B](A-_B) ok
• [A-_B](A-_B) ok
• [A_-B](A_-B) ok
• [A-_B](A_-B)

It works well in the javascript port of kramdown, i.e., the kramed.

$ echo "[A-_B](A_-B)" | kramed
<p><a href="A_-B">A-_B</a></p>

My environment is

• OS X El Capitan
• ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]
• gem 2.0.14
• kramdown 1.9.0

Thank you for reading this!
