Jgarber RedCloth

I'm using RedCloth 4.2.7. This is a bit of Textile I found in the edge Rails guides:

  Please use American English (_color_, _center_, _modularize_, etc.). See "a list of American and British English spelling differences here":http://en.wikipedia.org/wiki/American_and_British_English_spelling_differences.

What I get with RedCloth 4.2.7 and on http://redcloth.org/ is:

  <p>Please use American English (<em>color</em>, <em>center</em>, <em>modularize_, etc.). See <a href="http://en.wikipedia.org/wiki/American_and_British_English_spelling">a list of American and British English spelling differences here</a></em>differences.</p>

What I expect to get, and what I get on http://textile.thresholdstate.com/ is:

    <p>Please use American English (<em>color</em>, <em>center</em>, <em>modularize</em>, etc.). See <a href="http://en.wikipedia.org/wiki/American_and_British_English_spelling_differences">a list of American and British English spelling differences here</a>.</p>

It looks to my untrained eye that the underscore for the em around modularize is being too greedy and is going until the underscore between spelling and differences in the link, and then the link gets created after that?

The workaround I'm going to add to the Rails guide is using em tags instead of underscores; this generates the HTML I expect.

If there's any other information that would be helpful, please let me know. Thanks!
