299	Slugify shouldn't remove hyphens	gch@…	Adrian Holovaty	"Example python session:
{{{
>>> from django.core.defaultfilters import slugify
>>> slugify('Django Rocks!', None) 
'django-rocks'
>>> slugify('django-rocks', None)
'djangorocks'
}}}

Personally, I think it makes much more sense to not have it remove the hyphens.  Basically, you want slugify(slugify(slugify(X))) to equal slugify(X).

The simple fix here is the following diff
