Compare two Uniforum style .po files to check that both contain the same
set of msgid strings. The def.po file is an existing PO file with the
old translations. The ref.po file is the last created PO file
(generally by xgettext). This is useful for checking that you have
translated each and every message in your program. Where an exact match
cannot be found, fuzzy matching is used to produce better diagnostics.
