Write yourslef a handler application that takes those links and intelligently passes them along to your selected browser. You could probably do this in Applescript .. check the URL from http:// to the next / and check against a pre-defined list to see what browser you want to pass things along to. Also set that handler application as your default web browser (in Safari's preferences) -- which would then make it work from any program where you click a link (that's not already a browser).
But on second thought, I'd just copy and paste the links with issues as needed
Don't think you're going to find another way around this one really.
