Don't emit a newline in autoview. (#1466)

Browse Source 
The extra newline character makes it hard to use nu as part of an
external processing pipeline, since the extra character could taint the
results. For example:

```
$ nu -c 'echo test | xxd'
00000000: 7465 7374                                test
```

versus

```
nu -c 'echo test' | xxd
00000000: 7465 7374 0a                             test.
```
