Subject: [RFC PATCH v3 7/7] git-rebase: make --allow-empty-message the default
Date: Thu, 21 Jun 2018 08:00:23 -0700	[thread overview]
Message-ID: <20180621150023.23533-8-newren@gmail.com> (raw)
In-Reply-To: <20180621150023.23533-1-newren@gmail.com>

All rebase backends should behave the same with empty commit messages, but
currently do not.  am-based rebases already apply commits with an empty
commit message without stopping or requiring the user to specify an extra
flag.  Since am-based rebases are the default rebase type, and since it
appears no one has ever requested a --no-allow-empty-message flag to
change this behavior, make --allow-empty-message the default so that
merge-based and interactive-based rebases will behave the same.
