minify option

[MarcosCosmos]

Along with the existing pretty print, it may be useful to support minified code output.

I assume this won't be especially difficult since you're already using syntax trees?

[slava-sh]

I'm not aware of an existing Rust minifier.

The bundler currently runs rustfmt on a stringified TokenStream, which look like this:

fn main ( ) { println ! ( "Hello, world!" ) ; }

A simple way to "minify" the output would be to not run rustfmt and stringify the token stream in a way that doesn't include unnecessary whitespace.
