Forces Unity to write references and other inline mappings on one line, to help reduce version control noise.
When the Unity YAML writer reaches a line length of 80 characters it attempts to split the data over multiple lines.
To avoid unwanted version control changes, this setting forces the Unity writer to ignore the 80 character check when it writes inline mappings (also called flow mappings in the YAML spec).
