From 8d5247bd30bb971f1927e920648088f82646daf0 Mon Sep 17 00:00:00 2001 From: Philippe Proulx Date: Sun, 4 Aug 2019 00:24:06 -0400 Subject: [PATCH] cli, tests: rename "leftover" terms to "non-option" "Leftover" is a popt term, and we don't use popt anymore. Arguments which are not options are not leftover anymore: they are treated within the same loop as option arguments, and their position relative to option arguments are important, so we simply call them "non-option arguments". Note that "non-option" is also a term that getopt(1) and getopt(3) use.
