assert_eq! line too long on master

[radix]

rustfmt version: master @ 7da7764

I only have one line-too-long "sorry" bug in my codebase now, and it's on an assert_eq! line. rustfmt seems to be able to format these normally.

config:

chain_one_line_max = 100
fn_args_density = "Compressed"
fn_call_width = 100
max_width = 100
single_line_if_else_max_width = 100
struct_lit_width = 100
struct_variant_width = 100
tab_spaces = 2

line:

mod test {
  #[test]
  fn folderpath_from_str() {
    assert_eq!(FolderPath::from_str("/foo").unwrap(), FolderPath::from_vec(vec!["foo".to_string()]));
  }
}

and the warning:

Rustfmt failed at foo.rs:652: line exceeded maximum length (maximum: 100, found: 101) (sorry)

I'm sorry, I guess this is a dupe of #611

This may be hitting #1742.
