Yes, I think it's much better to display the invalid input along with the
error message. Not letting me see what I entered while simultaneously
telling me it was wrong would drive me batty. I don't think I'm alone
either (well, maybe I'd be alone in being driven batty by it), since
re-display of the input along with the error messages is the default work
flow supported by Django forms.
If you want to provide your own custom error messages for standard field
cleaning, see the doc on the error_messages parameter to a field:
http://docs.djangoproject.com/en/dev/ref/forms/fields/#django.forms.Field.error_messages
