Fixable: Some violations can be fixed by tooling

This rule is triggered when there is not a single newline character at the end of a file.

An example that triggers the rule:

# Heading

This file ends without a newline.[EOF]

To fix the violation, add a newline character to the end of the file:

# Heading

This file ends with a newline.
[EOF]

Rationale: Some programs have trouble with files that do not end with a newline.
