From 827f8305c4d5a0300c669dc57cc2920537bba757 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 17 Oct 2022 21:04:45 -0400 Subject: [PATCH] update-index: drop unused argc from do_reupdate() The parse-options callback for --again soaks up all remaining options by manipulating the parse_opt_ctx's argc and argv fields. Even though it has to look at both, the actual parsing happens via the do_reupdate() helper, which only looks at the argv half (by passing it along to parse_pathspec). So that helper doesn't need to see argc at all. Note that the helper does look at "argv + 1" without confirming that argc is greater than 0. We know this is correct because it is skipping past the actual "--again" string, which will always be present. However, to make what's going on more obvious, let's move that "+1" into the caller, which has the matching "-1" when fixing up the ctx's argc/argv.
