// Update_meta expects slashed.

update_meta should not be capped.

echo "</div>\n"; // #plugin-information-scrollable.

'advanced-cache.php'      => array( __( 'Advanced caching plugin.' ), 'WP_CACHE' ), // WP_CACHE.

$dropins['sunrise.php']        = array( __( 'Executed before Multisite is loaded.' ), 'SUNRISE' ); // SUNRISE.

These are not sentences. Maybe doesn't need punctuation. It's constants and a div's id attribute. Punctuation just feels weird here.
