#5033: Dynamic initial values for MultipleChoiceFields in newforms

The newforms documentation specifies that forms can be pre-populated with
dynamic values using an 'initial' dictionary. From the docs:
{{{
>>> class CommentForm(forms.Form):
... name = forms.CharField()
... url = forms.URLField()
... comment = forms.CharField()
>>> f = CommentForm(initial={'name': 'your username'}, auto_id=False)
>>> print f
<tr><th>Name:</th><td><input type="text" name="name" value="your username"
/></td></tr>
...
}}}
This works fine if the form element is a CharField as in the example
above. However, if the form element is a MultipleChoiceField, the initial
value is required to be the {{{id}}} of the object you're trying to select
- not the string representation as required for CharField, TextField et
al.
It's fairly obvious when you think about it, but it would have saved me
some time if the docs mentioned it.
