Well, the first use case was: my own old translations.  :)  Over 
time the precise translation of some words changed, and now I 
wished to update all of the old PO files to these better wordings.  
So the compendium contains the best wordings for often occurring 
messages, and they should overrule any existing translation.

That comes close, but it would not retain the fuzzies that could be 
present in example.nl.po.  And those should be retained.

The use case nowadays is: a new PO file arrives from the Translation 
Project -- the old PO file merged against a new POT file -- and it
contains some untranslated messages and several fuzzy translations.  
After matching against the compendium, any fuzzies that could not be 
exactly matched should be retained unchanged.
