Subject: [PATCH 08/14] git: support --list-cmds=list-<category>
Date: Sat, 19 May 2018 06:27:46 +0200 [thread overview]
Message-ID: <20180519042752.8666-9-pclouds@gmail.com> (raw)
In-Reply-To: <20180519042752.8666-1-pclouds@gmail.com>
This allows us to select any group of commands by a category defined
in command-list.txt. This is an internal/hidden option so we don't
have to be picky about the category name or worried about exposing too
much.
This will be used later by git-completion.bash to retrieve certain
command groups.
