D7582: rust-configparser: run rustfmt

[quark (Jun Wu)]

quark added a comment.


  We actually ran rustfmt, but it's an older version (rustfmt 1.3.0-stable (d334502 2019-06-09)) and I verified the code still formats under that particular version of rustfmt with empty `rustfmt.toml`. In other words, rustfmt itself seems to change over time.
