```
command.CommandChain.new(command: Command) -> Self
```

Start a chain from its first command.

Taking the first command here keeps a chain non-empty by construction:
an empty argv would make tmux act as a client rather than run anything.

## Example

```rust
use libtmux::{Command, CommandChain};

let chain = CommandChain::new(Command::new("list-sessions"));
assert_eq!(chain.command_count(), 1);
```
