Greetings.

**Preamble**:
Switching language by posting to set_language with an empty next parameter
causes a redirection to the REFERER url, as per the documentation.

**Description**:

What this means is that if language selection is made from a language-
neutral URL (say /about/), selecting english as language the redirection
in set_language will land the user to /en/about.

If - however - a new language selection (say de) is now made from
/en/about/, the landing spot will be (again) /en/about, rather than the
expected /de/about; the new language is now, however, memorised in the
user's session.

**What should happen:**
Invoking set_language from a language prefixed page with an empty next
parameter should redirect to the language-neutral URL, allowing the
session based url selection to kick in.

**What would help:**

Of course, being able to reference the current language-neutral url as the
next parameter to set_language would achieve the result. However,
language-neutral urls aren't availble in templates (or anywhere I looked);
so one's best hope is writing a custom template filter that strips the
language prefix from a URL and hen use the stripped request.path o
request.get_fulL_path as the next parameter to the POST.

Comment (by Claude Paroz):

This should have been fixed by #24122 / [aa5ab114e34645]. Isn't it the
same issue? Did we miss something?
