15307	slugify should take an optional max length	Jeremy Dunck	nobody	"A SlugField has a max_length of 50 by default, but the slugify template filter does not easily truncate.

Perhaps altering to something like this would be helpful:

{{{
SLUG_RE = re.compile('\-[^\-]*$')
def slugify_max(text, max_length=50):
        slug = slugify(text)
        last_len = len(slug)
        while len(slug) > max_length:
            slug = SLUG_RE.sub('', slug)

            # avoid infinite loop
            if len(slug) == last_len:
                break
            last_len = len(slug)
        slug = slug[:max_length] #hack off end if unable to nicely crop it.
        return slug
}}}
