This filter converts slashes to spaces in a a sting and then slugify's the result. However, it ignores leading and trailing slashes. For example, it can take something like this: 

/some/url/with-an-existing-slug/

And turn it into this: 

some-url-with-an-existing-slug

The filter was originally written to use the curent url as the disqus_identifier for Disqus comments. For example: 

{{ request.META.PATH_INFO|slug_and_slash_to_dash }}
