This patch turns on POSIXLY_CORRECT on the getopt parser to enforce options before commands. Users get a hint in such a case: # nft list ruleset -a Error: syntax error, options must be specified before commands nft list ruleset -a ^ ~~ This patch recovers 9fc71bc6b602 ("main: Fix for misleading error with negative chain priority"). Tests have been updated.
