Kenichi Maehashi ac8c549e2f [EC2] Cosmetic fix for usage of spark-ec2 --ebs-vol-num option 
The last line of the usage seems ugly.

```
$ spark-ec2 --help
<snip>
  --ebs-vol-num=EBS_VOL_NUM
                        Number of EBS volumes to attach to each node as
                        /vol[x]. The volumes will be deleted when the
                        instances terminate. Only possible on EBS-backed AMIs.
                        EBS volumes are only attached if --ebs-vol-size >
                        0.Only support up to 8 EBS volumes.
```

After applying this patch:

```
$ spark-ec2 --help
<snip>
  --ebs-vol-num=EBS_VOL_NUM
                        Number of EBS volumes to attach to each node as
                        /vol[x]. The volumes will be deleted when the
                        instances terminate. Only possible on EBS-backed AMIs.
                        EBS volumes are only attached if --ebs-vol-size > 0.
                        Only support up to 8 EBS volumes.
```

As this is a trivial thing I didn't create JIRA for this.
