Shell completion for --format with anonymous fields

In commit d81021ed265e I introduced shell completion for the `--format`
flag. This is a very nice way to complete go template field names.
However it did not work correct for anonymous fields. In this case the
child fields can be accessed directly from the parent.

For example:
```
type Anonymous struct {
   Field1 string
   Field2 string
   ...
}

type MyType struct {
    Anonymous
}

var s = MyType{}
```

Now if you want to access a field from the Anonymous struct you can just
do `s.Field1`. The same is allowed for go templates, using `{{.Field1}}`
should work. This commit adds this functionality, if the field is anonymous
read the child field names recursively and add them to the suggestions.
