Raises ValueError if ``msg`` is not in a batch;

This restriction may be relaxed in the future.

This means that you should not call ``getParentBatches``

|

For example, assume Limnoria received the following::

|

:irc.host BATCH +outer example.com/foo
|

@batch=outer :irc.host BATCH +inner example.com/bar

@batch=inner :nick!user@host PRIVMSG #channel :Hi

@batch=outer :irc.host BATCH -inner

:irc.host BATCH -outer

|

If you call getParentBatches on any of the middle three messages,
|
||||
you get ``[Batch(name='inner', ...), Batch(name='outer', ...)]``.
|
||||
And if you call getParentBatches on either the first or the last
|
||||
message, you get ``[Batch(name='outer', ...)]``
|
||||
|
||||
And you may only call `getParentBatches`` on the PRIVMSG

if only the first three messages were processed.
