You could try Pology, http://pology.nedohodnik.net/. It contains an actual
PO diffing script, poediff, where what "PO diff" means is documented in the
user guide. But it will not produce what you described as the ideal output;
this is very simple, and can be produced by the attached script using
Pology library.
