Zig fmt does not fix whitespace on one side of an operator

[silversquirl]

Zig Version

0.10.0-dev.1558+2af69710a

Steps to Reproduce

Try to run zig fmt on the following code:

pub fn main() void {
    a+ b;
}

Expected Behavior

The code should be reformatted to:

pub fn main() void{
    a + b;
}

Actual Behavior

<stdin>:2:6: error: binary operator `+` has whitespace on one side, but not the other.
    a+ b;
     ^

Probably caused by the implementation of #7399. Ideally this would be a compile error, but not a syntax error.

This is intended behavior: #7399 (comment)
