TextileParser renders some code differently

[d6y]

Raised by @serioga from lift/modules#6 and imported here.

The result of the calling

TextileParser.toHtml(":-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*")

is

<p>:-*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*:<del>*:</del>*</p>

Same string ":-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*" produces different result at http://www.textism.com/tools/textile/index.php:

<p>:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*:-*</p>
