    auto-indent: try to skip past strings and chars when walking backward
    
    Not perfect, but it's an incremental start.
    
    I still think we should try to write this differently in that we should
    try to build tokens as we walk backwards, or see if we can get clang to
    build us a partial translation unit for tokens.
