            Bug ID: 25018
           Summary: short lambda expressions don't mix well with
                    clang-format's interpretation of Allman braces
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

Clang-format's interpretation of Allman style braces includes forcing short
lambdas to put their braces on new lines. Of course the Allman style was
developed before lambdas were a thing in C++, so it doesn't specify how to
handle lambdas.

    foo([&]() { f(i); });

gets re-formatted as:

    foo([&]()
        {
            f(i);
        });


There ought to be an option to control this, similar to the other
'allowShortXxxOnOneLine' options.

There also ought to be an option for short classes/structs.
