Style for long type paths
Referred from https://github.com/rust-lang/rustfmt/pull/6494
A long type path could look like long_type_path::long_type_path::long_type_path::long_type_path::long_type_path::long_type_path::long_type_path::long_type_path::long_type_path::long_type_path::Long which currently would not get formatted, but this could exceed rustfmt's max_width setting.
How could this be handled?
