It is so hard to deal with locale module. I have great deal of translation file .po for drupal 4.7, and now i've got to translate all over again for drupal 5.x ??

Of course i can import the .po from 4.7, but in that translation file there are LOTS of unnecessary strings, which do not appear un current project. So, WHY there is no option "Update existing strings and DO NOT add new ones" ???? Is it really so hard to put something like that? I tried to make a hack in locale.inc, but no luck, it still imports string no matter what..
