Showdown cuts off reference-style links at 'Z'

[GoogleCodeExporter]

Markdown to reproduce the problem:

-------------

[URIs with Zs are cut off.][1]

  [1]: http://www.youtube.com/watch?v=7qh9AZVVDxw

--------------

The url-matching regular expression:

/^[ ]{0,3}\[(.+)\]:[ \t]*\n?[ \t]*<?(\S+?)>?[ \t]*\n?[ 
\t]*(?:(\n*)["(](.+?)[")][ \t]*)?(?:\n+|\Z)/gm

uses \Z, which is newline or end of subject for many regex engines, but literal 
'Z' in IE, Webkit, 
and Gecko. Removing "|\Z" from the expression resolves the issue.

PS: thank you for WMD! We've added some filtering for XSS, and are putting it 
to good use at

This has been fixed on the new version of WMD hosted on github
(http://github.com/derobins/wmd/tree/master).  Keep in mind that many of the WMD
options will be broken until v2.1 comes out in mid-Feb. 2009.

This seems like a bug in webkit and IE, but since Microsoft won't fix it...
