I agree with this change; you haven't only moved the \n outside the translated message but the flags themselves as well. This is good, as it allows changing the flags and white-space without affecting translations.

But a change like this does mean that all the translations have to be changed as well :/ Anyone up for the task?

I was wrong here -- the flags were already outside the translated text, it's just the \n that was moved out.

At least this makes it easier to fix up the other translations with a script.

You do need to re-run scripts/qt/extract_strings_qt.py after changing the strings in the core, so that the updated strings show up in the translations (are picked up by lupdate).

I'll write a little script to fix the translations.

Nils: how do changes get fed back into transifex?

Changes to transifex: It should happen automagically (transifex is fetching the source file using a cronjob), but I can also force an update.
