Shell commands break when repo directory contains spaces

[JonasOlson]

When the home directory borg_data_dir or the repository item.name contains spaces (or other special characters), shell commands such as these break:

command="cd {{ borg_data_dir }}/repos/{{ item.name }} &&
borg serve
--append-only
--restrict-to-path {{ borg_data_dir }}/repos/{{ item.name }}
",restrict'

Suggestion: Escape the strings using printf "%q".
