Config option to remove spaces between braces and (a) their contents (b) macro names

[berrymot]

In non-Rust, I treat braces like other delimiters and don't put internal spaces adjacent to them:

function five() {return 5;}

It'd be nice if I could do this in Rust as well, partially because I'm using the json crate and I'm used to writing inline JSON spacelessly and would rather not add spaces to make it look consistent with the rest of rustfmt.

i.e. I'd prefer

object!{foo: 12}

but currently have to

object! { foo: 12 }
