Each valid $lang was handled further down, but my patch was confusing,
especially when somebody wants to add more redirections.  Find
attached a revised patch with per-language redirection in only one
place, namely new procedure
`guix.gnu.org-redirects-for-each-language'.

Do I need to add a copyright header?  I hereby license/declare my
patch CC0 <https://creativecommons.org/publicdomain/zero/1.0/>.

In the previous patch I had missed some cases without /LANG like

/videos/everyday-use-of-gnu-guix,-part-one/index.html -> 
/$lang/videos/2020/everyday-use-of-gnu-guix-part-one/

Redirecting was unnecessary for

/videos/everyday-use-of-gnu-guix,-part-one/ -> 
/$lang/videos/2020/everyday-use-of-gnu-guix-part-one/

which already gets taken care of by

/videos/everyday-use-of-gnu-guix,-part-one -> 
/$lang/videos/2020/everyday-use-of-gnu-guix-part-one/

thanks to nginx location normalization.

Shall I push and then wait until someone guix system reconfigures
berlin?

Regards,
Florian
