Ah. Nother one that always confuses me:

The "Review" button when updates are available.

Review can mean a lot of things. E.g. "Look through a list of issues" (like in this case), but also "Double-check for correctness by being the second person taking a look" (reviewing patches, you know). The German translation of that button is... bad. Translator comment might help here...

Done.

I've reworked this string.

Done.

I think I've clarified this one.

My bad. I've unsplit them, and provided about 30 more strings fo you guys to translate.

This is a bodge to make the GUI look right when the user selects more than 5 packages. I'll rework.

I've added a comment. If you want to change translator comments like this, feel free to check them into svn like normal, or I can arrange a proper git account on our private server. Thanks dude.
