8888	fields_for_model() should produce fields in the same order as in parameter 'fields'	andrewl	nobody	"As per the ''TODO'' on line 126 of django/forms/models.py: ""''# TODO: if fields is provided, it would be nice to return fields in that order''""

A simple solution would be to maintain a temporary dictionary of the field names vs form fields as they are created, then at the end reorder them as per the fields parameter using the dictionary.

The modified code below for the method works, though it admittedly creates and maintains the temporary dictionary even if 'fields' is not defined... which obviously is a tad wasteful in such a case (new lines in method marked with '>>>').
