Some tools such as Git work better when files end with an empty line.

This rule simply generates an issue if it is missing.

For example, a Git diff looks like:

    .mybox {
      color: green;
    }
    \ No newline at end of file

if the empty line is missing at the end of the file.

Note that empty files are not checked against this rule.
