update_post_meta() and delete_post_meta() not using wp_is_post_revision() on $post_id, resulting in multiple meta rows and incorrect return values

[misterbisson]

add_post_meta() uses the following block of code to make sure the passed $post_id is a real post, not a revision:
`

make sure meta is added to the post, not a revision
if ( $the_post = wp_is_post_revision($post_id) )

$post_id = $the_post;

`

However, update_post_meta() and delete_post_meta() do not do that. The bug is present in trunk.

I guess i needed some practice setting file extensions and attaching files. Please delete all but the last.

Thanks for this! I've seen this in action but couldn't figure out what was going on.
