            Bug ID: 27640
           Summary: clang-format lambda block brace regression with
                    "BreakBeforeBraces: Allman"
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org

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.
