From be5fe2000df5c1110d8086e4704e1a90a64f7387 Mon Sep 17 00:00:00 2001 From: Aaron Lipman Date: Fri, 7 Aug 2020 17:58:36 -0400 Subject: [PATCH] cmd_bisect__helper: defer parsing no-checkout flag cmd_bisect__helper() is intended as a temporary shim layer serving as an interface for git-bisect.sh. This function and git-bisect.sh should eventually be replaced by a C implementation, cmd_bisect(), serving as an entrypoint for all "git bisect ..." shell commands: cmd_bisect() will only parse the first token following "git bisect", and dispatch the remaining args to the appropriate function ["bisect_start()", "bisect_next()", etc.]. Thus, cmd_bisect__helper() should not be responsible for parsing flags like --no-checkout. Instead, let the --no-checkout flag remain in the argv array, so it may be evaluated alongside the other options already parsed by bisect_start().
