From: Ville Skyttä Date: Thu, 8 Apr 2021 07:06:41 +0000 (+0300) Subject: completion: audit and guard $GIT_* against unset use X-Git-Tag: v2.32.0-rc0~84^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c5c0548d793edf4a6e319f237f3a01a1f093bbd7;p=thirdparty%2Fgit.git completion: audit and guard $GIT_* against unset use $GIT_COMPLETION_SHOW_ALL and $GIT_TESTING_ALL_COMMAND_LIST were used without guarding against them being unset, causing errors in nounset (set -u) mode. No other nounset-unsafe $GIT_* usages were found. While at it, remove a superfluous (duplicate) unset guard from $GIT_DIR in __git_find_repo_path.
