tags having problems with filtered variables using arguments with spacing

[killiands]

If you want to do something like this:
{% with activity.start_date|date:"l j F" as date1 %}
You'll get this error:
Exception Value: u'with' expected format is 'value as name'
This is due to this code:

    bits = list(token.split_contents())
    if len(bits) != 4 or bits[2] != "as":
        raise TemplateSyntaxError("%r expected format is 'value as name'" %
                                  bits[0])

First of all, maybe another bug: split_contents gave me a double "" on a filter as |cut:" ", so I replaced it with contents.split() which worked fine for me.
Then, this error: len(bits) !=4 is actually overkill. The tag works like this: 0 -> tagname, 1-> a variable with filter, 2 -> as, 3 -> newvar. Actually you should not check if the ' '-splitted content is 4 long, you should check if [1] passes the compile_filter, which will throw it's own error.

I tried to write a regex or iteration that really checked if you did really passed 1 variable + filter(s), but that really isn't trivial, and the compile_filter function's error is actually clear enough.

I added a patch + test for the {% with %} tag only at the moment (because that's where I encountered the problem). However, other tags have the problem also.

To be more precise, actually every tag that blindly splits on spaces will break on filter arguments with spaces in it. Such a patch would be quite large (all default tags, special tags & contrip apps tags).

Of course, Since the with tags works with my patch you can always work around this problem in other tags.
