This is also the wrong way to fix the problem.

We have output filters for a reason, people:

_filter_btrfs_subvol_delete()
{
	_filter_scratch | _filter_transcation_commit_default
}

Simply becomes:

_filter_btrfs_subvol_delete()
{
	_filter_scratch | _filter_transcation_commit_default | \
		sed -e 's/^Delete subvolume.*:/Delete subvolume/'
}

The golden output does not change - the filter simply removes the
part of the message that changed between versions.

Cheers,

Dave.
