Modify recent comments sidebar widget

[dotman]

my client doesn't want to show the commenters web url, only the link to the article ins the recent comments widget.

So this:

Watching Our Water Ways » Blog Archive » Climate bill generates quick and widespread response on Apollo Alliance Applauds Domestic Clean Energy Manufacturing Investments in American Clean Energy and Security Act

would become just this:

Apollo Alliance Applauds Domestic Clean Energy Manufacturing Investments in American Clean Energy and Security Act


Thus eliminating the off site link of the commenter. I've looked in the widgets.php file (is that the correct file to modify?), but now sure what code to change to make the above display as they would like. Could I get some guidance on this?

Thanks,
Doug
