Comment (by jsmoriss):

 Note that if anything else than a string is returned by
 `_wp_post_revision_field_{$meta_key}`, then PHP issues an error:

 {{{
 PHP Warning:  trim() expects parameter 1 to be string, array given in
 wordpress/wp-includes/formatting.php on line 5506
 }}}

 Since metadata can contain other types than just strings (like arrays, for
 example), it would be nice if WP could handle those types returned by
 `_wp_post_revision_field_{$meta_key}`.

 Here is an example of an array formatted using print_r() in the revisions
 page:

 And the code I used to hook those filters and format the metadata array:

 meta.php#L250-L319

 js.
