Even if .htaccess isn't writable, WP shouldn't prompt if there are no changes.

When you visit the permalinks settings screen, and .htaccess isn't writable, it prompts you to manually update. But it does that even if the current rules it is suggesting are already present. It should only prompt if the rules it is suggesting are different from what you have.
