Equal length method names

Would it be too much to ask that an option be provided which would make the method names all equal length by including whitespace on those that are shorter?

This clearly isn't a big deal and more whitespace is not a usual request but sometimes it's nice to be able to see things line up visually. I patched a copy locally with the following changes and I like the way it looks but being able to optionally configure `clim` to do this would be pretty cool:

```
ob.log = createLogger("LOG ", ob._prefixes, noFormat);
ob.info = createLogger("INFO ", ob._prefixes, noFormat);
ob.warn = createLogger("WARN ", ob._prefixes, noFormat);
ob.error = createLogger("ERROR", ob._prefixes, noFormat);
```

Just a thought...

Thanks!
