Mark Rousskov	b9e4174d8c	Do not run if rustfmt.toml does not exist ... distcheck (and generally publishing tarballs) will not package rustfmt.toml and we for now still support running tidy etc in those tarballs.	2019-12-22 07:44:09 -05:00
Mark Rousskov	dddd872427	Implement rustfmt running manually using ignore crate ... This replaces cargo-fmt with rustfmt with --skip-children which should allow us to format code without running into rust-lang/rustfmt#3930. This also bumps up the version of rustfmt used to a more recent one.	2019-12-21 20:23:55 -05:00
Adam Perry	a08c56295a	Implement ./x.py fmt [--check].	2019-12-21 20:23:39 -05:00
