ac: links broken when underscore in link text

[Skeeve]

What happened?

# test

## completely broken
[test_link](ac:)

## partly broken
[test_link](ac:test_link)
[test_link](<ac:test_link>)

Will produce:

<h1 id="test">test</h1>
<h2 id="completely-broken">completely broken</h2>
<p><ac:link><ri:page ri:content-title="test_"/><ac:plain-text-link-body><![CDATA[test_]]></ac:plain-text-link-body></ac:link></p>
<h2 id="partly-broken">partly broken</h2>
<p><ac:link><ri:page ri:content-title="test_link"/><ac:plain-text-link-body><![CDATA[test_]]></ac:plain-text-link-body></ac:link>
<ac:link><ri:page ri:content-title="test_link"/><ac:plain-text-link-body><![CDATA[test_]]></ac:plain-text-link-body></ac:link></p>

What did you expect to happen?

I expected the link text, as well as the link to read "test_link".

Instead, in the first version, everything after the "_" is cut off.

In the second and third version, the link is okay, but the link text itself is broken as before.
