Rustfmt: [unstable option] control_brace_style

Tracking issue for unstable option: control_brace_style

[JosephTLyons]

Would love to have this feature stabilized. Having else statements on the same line as the closing brace of an if block is the only thing about rustfmt that bothers me, so this is the only setting I have in my rustfmt.toml file.

Does anyone know what's holding this up from being stabilized? Any information would be appreciated. Thank you!
