        Fix for this bug:

        <rdar://problem/3800346> Inserting newline in BR after block not working

        * khtml/editing/htmlediting_impl.cpp:
        (khtml::InputNewlineCommandImpl::doApply): The code to insert the "extra" BR at the end
        of blocks (hack done to make BRs show up when they appear at the ends of blocks) did not
        cover this one quirky case where the insertion point can be placed in a BR at the end of
        a block that does actually render. Now the input newline code can handle this addtional
        case.
        * layout-tests/editing/selection/insert-3800346-fix-expected.txt: Added.
        * layout-tests/editing/selection/insert-3800346-fix.html: Added.
