Regression >=0.10: Behavior with empty string

[akiradeveloper]

This code panics with "No such file or directory" with version 0.10 or above.

use cmd_lib::*;
fn main() {
    dbg!(run_cmd!(ls));
    let options = "";
    dbg!(run_cmd!(ls $options));
}

I think ls "" should be interpreted as ls in this library.

Is this your intention? and is there some workaround?

Thanks for reporting this. Yeah, it is better to skip the empty arguments.
