/// Minimal reproducible code posted by user `mkeeter` to demonstrate `clap` issue 4707
/// which we are experiencing at time of creation of this script.
/// https://github.com/clap-rs/clap/issues/4707
///
/// To reproduce the error, run `cargo run demo/test_clap_4707.rs -- --write --show-hex`
/// Correct behaviour would be:
/// error: the following required arguments were not provided:
///  --read
/// Incorrect behaviour is that the command runs without an error.
//# Purpose: test if the error exists, then periodically to see if it persists.
//# Categories: crates, testing
//# Sample arguments: `-- --write --show-hex`
