Bug#616654: p.d.o: untranslatable top menu

Dear all
I'm not sure about the status of this bug...

https://packages.debian.org/en/wheezy/ for example, shows that the page
is available in several other languages, but when I click on them (for
example https://packages.debian.org/fr/wheezy/ ), I still see the page
in English.

I've reviewed
https://anonscm.debian.org/cgit/webwml/packages.git/tree/templates/html/head.tmpl
and I cannot see the lines corresponding to the titles, nor translatable
nor untranslatable.

OTOH, I'm Spanish translator and the Spanish language is not shown in
the list of available languages. I would like to provide translations to
fix that, but I'm not sure how to proceed, where are the current
templates, in which branch should I commit...

Thanks
