Subject: [PATCH v5 06/10] completion: implement and use --list-cmds=main,others
Date: Sun, 29 Apr 2018 20:18:40 +0200	[thread overview]
Message-ID: <20180429181844.21325-7-pclouds@gmail.com> (raw)
In-Reply-To: <20180429181844.21325-1-pclouds@gmail.com>

Instead of parsing "git help -a" output, which is tricky to get right,
less elegant and also slow, make git provide the list in a
machine-friendly form. This adds two separate listing types, main and
others, instead of just "all" for more flexibility.
