Auto-URLs are breaking with any url that has an underscore

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enable auto-url parsing
2. Use this: http://www.youtube.com/watch?v=wsdy_rct6uo
3. Watch DoItalicsAndBold replace the underscores with <em> tags

What is the expected output? What do you see instead?
Expected:  "<a 
href=\"http://www.youtube.com/watch?v=wsdy_rct6uo\">http://www.youtube.com/watch
?v=wsdy_rct6uo</a>"

What I see: 

"<a 
href=\"http://www.youtube.com/watch?v=wsdy<em>rct6uo\">http://www.youtube.com/wa
tch?v=wsdy</em>rct6uo</a>"

What version of the product are you using? On what operating system?

Currently testing a solution - Moving DoItalicsAndBold above DoAnchors and 
DoAutoLinks
