Hmm, I think you should check for form errors in the template and then style your label accordingly. IMHO this shouldn't be put into trunk simply because it forces a certain style onto the Django user.
What if he/she want his/her label to be a Pony when a field is required?

About your patch:
It hasn't got tests, check the contributing guidelines in the docs.

Basically a duplicate of #3512 and #3515 (this is just one specialised case of those). One day we'll make a decision about how to handle those cases.
