when i pass "-o foldattributes" to po4a-translate, it translates and unfolds 
everything correctly.
when i don't, it unfolds attributes but it doesn't translate strings that 
contained foldable attributes (it does translate other standard strings, 
however). it's indeed confusing and a check would be good to avoid this 
mistake.

sure, these look good, just pick the easier to implement. :)
