This space was introduced, presumably unintentionally, in b3b18d1621 (advice: revamp advise API, 2020-03-02) I notice this space due to confuse diff outputs while doing some changes to enum advice_type. As a reference, a recent change we have to that enum is: $ git show 35f0383 [ ... ] diff --git a/advice.h b/advice.h index 0f584163f5..2affbe1426 100644 --- a/advice.h +++ b/advice.h @@ -49,6 +49,7 @@ struct string_list; ADVICE_UPDATE_SPARSE_PATH, ADVICE_WAITING_FOR_EDITOR, ADVICE_SKIPPED_CHERRY_PICKS, + ADVICE_WORKTREE_ADD_ORPHAN, }; Note the hunk header, instead of a much more expected: @@ -49,6 +49,7 @@ enum advice_type Signed-off-by: Rubén Justo <rjusto@xxxxxxxxx> --- advice.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/advice.h b/advice.h index 9396bcdcf1..74d44d1156 100644 --- a/advice.h +++ b/advice.h @@ -10,7 +10,7 @@ struct string_list; * Add the new config variable to Documentation/config/advice.txt. * Call advise_if_enabled to print your advice. */ - enum advice_type { +enum advice_type { ADVICE_ADD_EMBEDDED_REPO, ADVICE_ADD_EMPTY_PATHSPEC, ADVICE_ADD_IGNORED_FILE, -- 2.42.0
