            Bug ID: 24705
           Summary: Regression? 3.7 and 3.8 eats line-break between
                    function definitions
           Product: clang
           Version: 3.7
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

clang-format36 doesn't touch the following code:

namespace foo
{
    int one() noexcept { return 1; }

    int two() noexcept { return 2; }
}

But clang-format37 and clang-format-devel (3.8, built today from ports) turns
it into:

namespace foo
{
    int one() noexcept { return 1; }
    int two() noexcept { return 2; }
}
