If this a significantly better way to do this than the old way highlighyed by andy on wp-testers:

​http://trac.wordpress.org/browser/tags/2.3.2/wp-includes/js/tinymce/themes/advanced/jscripts/link.js#L28

Changes to TinyMCE in prior versions were flagged with "WordPress". A
search of the codebase should find any others that might have been
lost in the update.

Better? No, it's about the same. However the file /tinymce/themes/advanced/js/link.js is completely changed in 3.0, so the select() is moved to inline js (where it would probably need less maintenance).

Also some of the enhancements made to TinyMCE 2.x in WordPress are now part of TinyMCE 3.0, like the auto-selecting of the first text field in a popup, closing of the popup when pressing Esc, etc.
