        <div>
        <pre>clang-format 3.7 correctly formatted the following code:

void x()
{
    return something([](auto) -> decltype(auto) 
    {
        something();
        something();
    });
}

Note the breaks inside the lambda body.



clang-format 3.9 does not respect the Allman setting for lambda bodies:

void x()
{
    return something([](auto) -> decltype(auto) {
        something();
        something();
    });
}



I think that version one is the correct hehavior (and is the one I desire).
Please add a flag like "BreakBeforeLambdaBody" in order to accomodate multiple
coding styles.</pre>
