Uncrustify and Lambdas

[manpen]

The indention configured in uncrustify makes usage of lambdas (especially as function parameters) impractical.

auto local_queue_at_max_size = [&]() {
                                   return foo;
                               };

Where the following solution would be much better

auto local_queue_at_max_size = [&]() {
    return foo;
};

Yes this behaviour is extremely aggravating. @bingmann plz fix in Thrill, too.
