The single_line_if_else_max_width is one of many configuration options that could use some improvements to it's documentation. It would be great to:

• Add code snippets to highlight the functionality this option provides
• Describe that the behavior of this option changes when version=Two is set.

Additionally, some tests for the options should be added to tests/source/configs/ and tests/target/configs/. See the Create test cases section of the Contributing guide for more details. It would be great to have test cases for both version=One and version=Two.
