Tracking issue for unstable option: normalize_comments

[Veetaha]

@scampi is there any plan to stabilize this option? At least ensuring single whitespace after // would be very useful for my use-case...

[ia0]

With rustfmt 1.4.22-nightly (97d0301 2020-10-04) it looks like enabling this option does the opposite of what the documentation says.

enum Foo {
    X1,
    // X2,
    // X3,
}

gives

enum Foo {
    X1,
    /* X2,
     * X3, */
}

instead of doing nothing.

Is that expected?

I think @ia0's issue was resolved by #4909

I really wish that we could have at least an option to ensure each // comment is followed by no fewer than 1 (white)space character, and have that stabilized. It's a hassle needing to nitpick that sort of thing for //comments like this in the PRs our open source project receives. Could a descoped version of this setting, that does just that (which should hopefully be trivial to ensure correctness for?), be released in a stable channel?
