Change --only to include comments portion ?

Let's say I have the following in my sup file
```
  production:
    hosts:
      - root@172.106.9.243  # 2tb ashburn
```

If I run `sup --only 172.106.9.243 production date', then a match occurs

If I run `sup --only ashburn production date', then a match WILL NOT occur

How do the maintainers feel about a PR to change 'only' so the comments can be matched against?
