 I take the opportunity to say this is my first ticket (issue) posted for
 Django.

 As you can search in the docs
 (https://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-
 options). There is no documentation about the `ModelAdmin.save_form`
 method but is being called multiple times (lines 1763 and 1575 in
 `django.contrib.admin.options`).

 On the other hand, `ModelAdmin.save_form` calls the `form.save` method and
 `ModelAdmin.save_model` calls the `obj.save` method, but
 `ModelAdmin.save_form` and `ModelAdmin.save_model` are called in the same
 flow (lines 1763,1764 and 1575,1580 in `django.contrib.admin.options`),
 i.e., both can be called in serial leading to multiple saves of the same
 object. Maybe a better documentation of that, a suggestion of which to
 use, and if it's possible an optimization of those calls would be great.

 I'm all ears to your comments.
