Make CharField/TextField remove newlines from input

[Jakub Kleň]

It seems to me Django should automatically remove newlines from input type="text" fields. Browsers seem to prevent users from entering newlines in those types of fields, but that's not something we should rely on, and the behaviour should be consistent between Django and web browsers. It seems to me it applies to almost all django.forms.widgets.Input widgets.

I don't think there would be consensus for Django to modify input like that -- see ticket:6362#comment:43, for example. Remember that input might come from APIs as well. You could write to the DevelopersMailingList if you want to get other opinions.

As a temporary solution, I implemented this change in django.forms.widgets.Input.value_from_datadict as I think that's the right place for it. Seems like it's widget related to me, it's the widget that doesn't support newlines, and the implementation was really simple. I would be really happy to also see this change in Django.

I also started a discussion for this here:
