Hi guix,

a week ago Luis nicely redesigned how videos are displayed on the Guix
website
<https://lists.gnu.org/archive/html/guix-patches/2021-07/msg00005.html>.
(Because the old CSS stylesheets are cached by the browser, the
website displayed videos wrongly for a day though.)

This patch adds redirects for the guix website from the old video URLs
like

/LANG/videos/everyday-use-of-gnu-guix,-part-one/index.html
/LANG/videos/everyday-use-of-gnu-guix,-part-one/
/LANG/videos/everyday-use-of-gnu-guix,-part-one

to the new

/LANG/videos/2020/everyday-use-of-gnu-guix-part-one/

but maybe the patch is too ugly because that’s code duplication to
have three added redirections for each video.  Note that my old
videos page actually linked to
</LANG/videos/everyday-use-of-gnu-guix,-part-one/index.html> and not
</LANG/videos/everyday-use-of-gnu-guix,-part-one/> as usual.

Shall I push it as-is to guix/maintenance.git,

or do you think it would be better to rewrite the redirect procedure
to return a list to redirect every URL with suffixes

""
"/"
"/index.html"

and change guix.gnu.org-locations accordingly to flatten the location
list?

The patch was tested on a VM of berlin.scm with some services, file
systems and SSL removed and I’m confident it does what it should.

Regards,
Florian
