[Learned Lesson] Plugin adding using meta on a post and revisions

With 2.6, I ran into some issues with a plugin I am creating which saves its data with in the post meta. The problem is the revision system because my plugin is passed the revision ID (not the post ID) when the post is saved. Here is the code snippet I found to translate the revision ID to the post ID.

// saving
if ($the_post = wp_is_post_revision($post_id)){
   $post_id = $the_post;
}
add_post_meta($post_id, $key, $value, true) or update_post_meta($post_id, $key, $value);

// retrieving
if ($the_post = wp_is_post_revision($post_id)){
   $post_id = $the_post;
}
get_post_meta($post_id, $key, true);

It would be great if this part of the API is updated to give control regarding the revisions.
