`"bring item"` broken for indented lists

[pokey]

In the following markdown:

- aaa
  - bbb
  - ccc
  - ddd
  - eee

Saying "bring item each after bat" results in the following:

- aaa
  - bbb
  - ccc
    eee
  - ddd
  - eee

It seems like this bug is in part because the leading indentation of ccc is included in item - bbb (#1199), but in addition, it seems that the range is being extended to the end of the line.
