Positional Arguments and Options: Order matters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Borg only supports taking options (``-v`` and ``--list`` in the example)
to the left or right of all positional arguments (``repo::archive`` and ``path``
in the example), but not in between them:
::
borg extract -v --list repo::archive path # good and preferred
borg extract repo::archive path -v --list # also works
borg extract -v repo::archive path --list # works, but ugly
borg extract repo::archive -v --list path # BAD
This is due to a problem in the argparse module: http://bugs.python.org/issue15112
