Indenting doc-comments should leave comment symbol at start of line

[dylwil3]

Love the latest release! One small tweak would help improve the experience around doc-comments. At the moment if I have something like (in Rust):

\\! My module documentation
\\! Something I meant to indent

and I try to indent the second line with >, I get

\\! My module documentation
    \\! Something I meant to indent

but I actually want

\\! My module documentation
\\!     Something I meant to indent

Apologies if this has already been requested or if there is a simple way around this that I don't know about.

Thanks for helix, it's great!

Hm... I'm a bit unsure about this one.
Imagine you have the following code block:

fn main() {
// epic comment
let a = 10;
}

and you would like to fix the indentation by using >. What I'd do, is selecting the comment and the let line and press >.
Now, with your suggested behaviour, it would result into this:

fn main() {
//     epic comment
    let a = 10;
}

Which is very likely not the wanted outcome.
Hm... maybe a new keybinding can be added where you need to press > + Alt which will only shift text within comments?

Maybe that case could also be addressed with the following heuristic: only use the new behavior when all selected lines are comments.

Then you could select both // epic comment and let a = 10; in your example, before pressing >. That would avoid the need for an override key. Incidentally, this would be consistent with the new behavior for o/O, where (as far as I know?) there isn't really an override key.
