Discrepancy between argfile and shell when processing escaped characters

[utikeev]

Let's say I have the following command that simply prints the passed multiple arguments.

class Hello : CliktCommand() {
    val words by argument().multiple()

    override fun run() {
        println(words)
    }
}

Calling ./hello a b "'"c"'" in sh, bash, zsh correctly produces [a, b, 'c'] as the output.

However, if I put the exact same arguments inside the argfile:

a b "'"c"'"

calling ./hello @argfile produces [a, b, ', c'] separating the first quote into a separate argument.

Thanks for the report, this should be easy to fix.
