Currently it's 100% translated and I suspect all strings are simply 
copied as is:

2524 (100.0%) translated, 0 (0.0%) fuzzy, 0 (0.0%) untranslated, total 2524


Where it gets a bit strange is that en.po is partially translated even 
though it claims to be 'Automatically Generated' (so I'd expect either 
0% or 100%):

1748 (69.3%) translated, 0 (0.0%) fuzzy, 776 (30.7%) untranslated, total 2524


My understanding it that en.po contains the British translation and is 
treated as just another translation. So instead of containing just the 
strings that need to be different, all the other strings are copied as 
well by the translators so they know what has been checked already.
