fix: correctly generate network if path has spaces (#357)

Parsing of output of the `ls-files` commands was splitting paths with spaces.
It is literally the difference show below.

```python
>>> s = 'string space\nother line\n'
>>> s.split()
['string', 'space', 'other', 'line']
>>> s.split('\n')
['string space', 'other line', '']
```
