Subject: [PATCH v2 1/2] parse-options: add --git-completion-helper-all
Date: Wed, 19 Aug 2020 23:06:08 +0000 [thread overview]
Message-ID: <20200819230523.773348-2-rtzoeller@rtzoeller.com> (raw)
In-Reply-To: <20200819175047.692962-1-rtzoeller@rtzoeller.com>
--git-completion-helper excludes hidden options, such as --allow-empty
for git commit. This is typically helpful, but occasionally we want
auto-completion for obscure flags. --git-completion-helper-all returns
all options, even if they are marked as hidden or nocomplete.
