Useful when generating the borgmatic configuration file with
configuration management and before moving the generated file in place
checking if it is actually valid.
This bug is can be quite annoying because when you accidentally used
something like:
```ini
[location]
source_directories: backup_one backup_two
; A (Additional space here)
```
It would call Attic/Borg with ('backup_one', '', 'backup_two') which in
turn backups your whole $PWD.
