From 0089521cacd99db8018b7a31e205dad0bf0738c7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 20 May 2018 20:39:57 +0200 Subject: git.c: convert --list-* to --list-cmds=* MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Even if these are hidden options, let's make them a bit more generic since we're introducing more listing types shortly. The code is structured to allow combining multiple listing types together because we will soon add more types the 'builtins'. 'parseopt' remains separate because it has separate (SPC) to match git-completion.bash needs and will not combine with others.
