* Usage: php trim-po.php xx_YY.po
* Prints a copy of xx_YY.po, omitting all translations that match xx.po.
* If not of form xx_YY.po or xx.po does not exist then trim any translations
* where msgid == msgstr (applies mainly to en_*).
* Both cases also print warnings for any translation hints that are not
* handled in this translation (and will appear in the application).
