From a5ef35052e66721e9f943b2b9a91176536b4d896 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 1 Mar 2021 10:28:43 -0500 Subject: storage-daemon: report unexpected arguments on the fly If the first character of optstring is '-', then each nonoption argv element is handled as if it were the argument of an option with character code 1. This removes the reordering of the argv array, and enables usage of loc_set_cmdline to provide better error messages.
