'vim' has two configuration options ('splitbelow' and 'splitright') that change the way the 'split' command behaves. When they are set, the commands that the layout engine generates no longer work as expected.
In order to fix this we can append special keyword 'letfabove' to each 'split' and 'vertical split' subcommand found inside the command string generated by the layout engine.
This works because whatever comes after 'leftabove' will temporally ignore settings 'splitbelow' and 'splitright'.
