path-urls documentation implies implicit converter-types

[Christopher Schäpers]

The documentation for the new path() urls somewhat implies that if you have a named value in an url without a converter type, but with the name of a converter-type it takes the name of the value, and uses it as its converter-type.

E.g.

path('articles/<slug>/', …)

would only match a slug, and would pass the value on as "slug".
(As seen here: ​https://docs.djangoproject.com/en/dev/topics/http/urls/#example )

This is wrong, as mentioned below (easy to miss, if you're eager to test stuff out):

If a converter isn’t included, any string, excluding a / character, is matched.

---

However it doesn't help, that the example uses "slug" as a name, and states

/articles/2003/03/building-a-django-site/

would match the last example, even though

/articles/2003/03/building+a~django@site/

would match it just as well.

---

Simple fix would be to just change the example from

articles/<int:year>/<int:month>/<slug>/

to

articles/<int:year>/<int:month>/<slug:slug>/

because I suppose the implicit converter types aren't a feature of 2.0.

(If someone points me to the right repo, I can do the little documentation change myself)
