[translations] be careful of placeholders: % ! @

Hi everybody, I would like to point out that Drupal 5 use % ! @ as placeholders in strings, not only % as in previous versions. So be careful about this characters in your translation. I personally noticed that sometime poedit, while updating 4.7 translations with 5.0 pot, consider the same string if only changes the placeholders, marking the string as already translated. Cheers, Fabio
