If the initial buffer ends with one or more empty lines, vim-clang-format
will let one single empty line. This is not the clang-format behavior,
which do not let any empty line at the end of the file.
When the value is 1, vim-clang-format ensures that formatted buffer does
end with any empty lines.
The default value is 0 (which is the historical vim-clang-format
behavior).
