Function invocation 

pub fn invocation(
    bin: &str,
    config_paths: &[PathBuf],
    account: Option<&str>,
) -> String

Available on crate feature terminal only.

Builds the invocation a printed command starts with: bin, then one -c per configuration path and -a when an account is named, each value quoted.

It carries the -c and -a the binary ran with, so the command reaches the same configuration and account rather than the default ones.
