Ah.  That makes sense then.  I just wanted to make sure it wasn't 
something strange happening.

The only problem is that I've made lots of small changes to the 
translations (fixing formatting, newlines, and printf arguments).  I 
have no idea who made each of the individual translations, and since I 
haven't modified the Last-Translator field in the po file, that means 
I've really mixed up the translation assignments...

I don't have any good suggestions, but for the time being, I will try 
and keep my own list of translators and not delete any..
