[tryton] Get older Tryton version (2.8) via "hg nclone"

[aeneas Winterhalter]

Hello,

I always istalled tryton via "hg nclone http://hg.tryton.org/2.8/trytond/"; 
but "http://hg.tryton.org/2.8/trytond/"; redirects me to "
http://hg.tryton.org/trytond/"; and this is the recent version. Is there a 
Repository for Tryton 2.8?
