Aliases with "--" don't work. Is this by design?

[gbsmith]

If I have this

 override fun aliases(): Map<String, List<String>> = mapOf(
        "--list" to listOf("--command=list"),
        "ls" to listOf("--command=list"),
    )

The ls alias works as expected, while --list spits out

Error: no such option --list
Error: missing option --command

Is this deliberate? Or is this necessary due to the way the args are parsed?

Fixed in #536
