Comment (by dd32):

 Personally I see it as a bug that `current_user_can( 'edit_post', false )`
 would return anything other than `false`. If you want a primitive
 capability, you'd use `edit_posts`, calling `edit_post` without providing
 a valid post should always be false.

 However, failing to be able to edit a comment where the post doesn't exist
 does seem like a legitimate bug.
 It seems like, that `edit_comment` should use `edit_post` when the post
 exists, and failing that, falling back to `edit_posts`. `edit_posts` feels
 incorrect here though, but is the only real choice for backwards
 compatibility.
