This was incorrectly ported from Rust to Go. When provided, `treefmt` will take the contents of stdin and place them into the file provided with the `--stdin` flag, then format it according to the configured formatters. If the file doesn't exist it is created. If it exists, it is first truncated and then populated with stdin. Signed-off-by: Brian McGee <brian@bmcgee.ie>
