fix documetation after merge of model-validation to trunk

[Alex Koval]

In documentation here:

​http://docs.djangoproject.com/en/dev/ref/forms/fields/#charfield

its said that valid error message keys are: required, max_length, min_length

While in fact, in trunk code those variables are:

• limit_value
• show_value

(see ​http://code.djangoproject.com/browser/django/trunk/django/core/validators.py#L108)

Documentation and code mismatch.

Near as I can tell the doc is still correct:
