```
command.Command.sensitive_arg(mut, argument: impl Into<OsString>) -> Self
```

Append one sensitive logical argument.

The value is dispatched exactly but diagnostics use one
length-independent redaction marker.

## Example

```rust
use libtmux::Command;

let command = Command::new("set-environment")
    .arg("TOKEN")
    .sensitive_arg("secret");
assert_eq!(command.summary().sensitive_argument_count(), 1);
assert!(!command.summary().to_string().contains("secret"));
```
