Update *.po with git.pot?

When a translation round starts for a Git release, the git.pot file will be updated and translators msgmerge their .po-files accordingly before translating. This results in a huge change to the .po-file as line numbers and stuff gets updated.

Since translations are made in one commit, this commit is messed up with the msgmerge update so when you look at the commit later, you'll have a hard time to find out what the actual changes in translations were.

We could improve this by making git.pot-updates update the *.po files as well, so further updates from translators will only contain actual translations. I think this is what the gitk project does. It will make the history of *.po-files much more readable.
