tag -l breaks filenames

Happens after the second result.

```
user@localhost ~ $ mkdir test
user@localhost ~ $ cd test 
user@localhost ~/test $ echo 23 > a 
user@localhost ~/test $ echo 23 > b
user@localhost ~/test $ echo 23 > c
user@localhost ~/test $ ag 23
c
[1] 1:23

b
[2] 1:23

a
[3] 1:23
user@localhost ~/test $ ag 23 -l
c
ba
user@localhost ~/test $ unalias ag
user@localhost ~/test $ ag 23 -l  
c
a
b
```
