Incorrectly adds space in macro parameters

[k-bx]

I'm using rust_cmd_lib to do some command execution, and on this simple command:

    let id = run_fun!(id -u).context(h!())?;

rustfmt formats it to:

    let id = run_fun!(id - u).context(h!())?;

Which is definitely not what I want.

Macro formatting is tough. It might be the case that id -u is getting parsed as a binary expression, and that's why it's getting formatted as id - u.

If you're using nightly rustfmt you can use the skip_macro_invocations config to disable formatting on the run_fun! macro calls.

Apologies for a newbie question. But can I disable rustfmt on per-module or per-function level somehow? It would solve most of the problems. Could not find solution via search.

You could probably add #![rustfmt::skip] to the files you want rustfmt to ignore
