Rustfmt is creating my code uncompilable

[manio]

Hi. I think I found a bug in rust fmt.
The following good and compilable code:

        info!(//debug
            "{}: sending function_code={:04x} data={:04x} crc=0x{:04X} data={:02X?}",
            self.name, function_code, data, crc, output_cmd
        );

is wrongly formatted to this:

        info!(
            //debug "{}: sending function_code={:04x} data={:04x} crc=0x{:04X} data={:02X?}",
            self.name, function_code, data, crc, output_cmd
        );
