I've found that texdoc now only seems to recognise LC_ALL. Previously it 
picked up the localisation setting correctly without LC_ALL set. I have 
LANG=en_GB.utf8 and LANGUAGE=en which used to be sufficient to select 
English documentation. (There was a thread about it a few months ago.)

In the end I created ~/texmf/texdoc/texdoc.cnf and put the following 
line in it:

lang = en
