kwargs dict is not filled with kwargs

Hi Michele. Thanks for your great job!

Wrote a small decorator(django by default caches everything in 'default' cache):

def filesystem_cache(key_prefix, cache_time=None):
    """
    Caches function based on key_prefix and function args/kwargs.
    Stores function result in filesystem cache for a certain cache_time.
    """
    if cache_time:
        FILESYSTEM_CACHE_TIME = cache_time
    else:
        FILESYSTEM_CACHE_TIME = settings.CACHES['filesystem'].get('TIMEOUT')

    @decorator
    def wrapfunc(func, *args, **kwargs):
        ignore_cache = kwargs.pop('_ignore_cache', False)
        full_args = list()
        full_args.extend(args)
        for k, v in kwargs.items():
            full_args.append('%s:%s' % (str(k), str(v)))
        md5_args = md5_constructor(u':'.join([urlquote(var) for var in full_args]))
        cache_key = 'template.cache.%s.%s' % (key_prefix, md5_args.hexdigest())
        filesystem_cache = get_cache(FILESYSTEM_CACHE_NAME)
        cached_value = filesystem_cache.get(cache_key)
        if cached_value and not ignore_cache:
            # if cached value exists - return it
            return cached_value
        result = func(*args, **kwargs)
        filesystem_cache.set(cache_key, result, FILESYSTEM_CACHE_TIME)
        return result
    return wrapfunc

Everything works ok except that all args and kwargs for function fall into args 
section : 
In [2]: @filesystem_cache('bla')
   ...: def hello(a,b,c, d=10,e=12):
   ...:     print a
   ...:     print b
   ...:     print c
   ...:     print d
   ...:     return e

In [3]: hello(5,6,7, d=11,e=18)
> /home/dev/imax/mws/src/imax_main/utils.py(29)wrapfunc()
-> md5_args = md5_constructor(u':'.join([urlquote(var) for var in full_args]))
(Pdb) l
 24             full_args = list()
 25             full_args.extend(args)
 26             for k, v in kwargs.items():
 27                 full_args.append('%s:%s' % (str(k), str(v)))
 28             import pdb; pdb.set_trace()
 29  ->         md5_args = md5_constructor(u':'.join([urlquote(var) for var in full_args]))
 30             cache_key = 'template.cache.%s.%s' % (key_prefix, md5_args.hexdigest())
 31             filesystem_cache = get_cache(FILESYSTEM_CACHE_NAME)
 32             cached_value = filesystem_cache.get(cache_key)
 33             if cached_value and not ignore_cache:
 34                 # if cached value exists - return it
(Pdb) args
func = <function hello at 0xa63f454>
args = (5, 6, 7, 11, 18)
kwargs = {}
(Pdb) kwargs
{}

Why d and e kwargs are in args array ? Thanks !
