Arguments with equals are incorrectly interpreted as options

[eschrock]

We are trying to use clikt for a command that can take a URL as an argument. This can have query parameters, but it seems like any argument with a "=" in the name is treated as an argument. For example:

class Hello : CliktCommand() {
    val arg by argument()
    override fun run() {
        echo("Argument: $arg")
    }
}

fun main(args: Array<String>) = Hello().main(args)

$ hello foo
Argument: foo
$ hello foo=bar
Error: no such option: "foo".

The docs state:

Clikt normally parses any value that starts with punctuation as an option, which allows users to intermix options and arguments. However, sometimes you need to pass a value that starts with punctuation to an argument. For example, you might have a file named -file.txt that you want to use as an argument.

However, in this case, we do not have any starting punctuation, so I don't know why it's trying to parse it as an option.

While we can ask users to use the "--" delimeter, it means that it will effectively always need to be used. This is a pretty annoying experience.

I've never seen a command that behaves this way, so I'm assuming this is a bug. If this is indeed the desired behavior, could a mechanism be provided to disable it?

That's definitely a bug. Thanks for the well written report!
