Subject: [PATCH v13 18/20] index-helper: optionally automatically run
Date: Sun, 26 Jun 2016 00:14:22 -0400 [thread overview]
Message-ID: <1466914464-10358-18-git-send-email-novalis@novalis.org> (raw)
In-Reply-To: <1466914464-10358-1-git-send-email-novalis@novalis.org>
From: David Turner <dturner@twopensource.com>
Introduce a new config option, indexhelper.autorun, to automatically
run git index-helper before starting up a builtin git command. This
enables users to keep index-helper running without manual
intervention.
