Updating svn head, trunk and branch.

[Anna Jonna Armannsdottir <annaj hi is>]

I do not quite understand the advice given in 
Other hints in the LocalisationGuide. It says:  
http://live.gnome.org/TranslationProject/LocalisationGuide#head-a3983f3a5960c2e1d2ef4dae83e9c8a200067216

I presume that a translator can only concentrate on one .po file, at 
a time. If that is correct, then the translator must choose between 
branches and trunk/head. 
Is it a better choice to always stick tho the trunk, and then update 
the branches later. 
Or is it better to update one branch or several branches, and then
updating the trunk/head?
