Subject: [PATCH 3/6] commit: add a reword suboption to --fixup
Date: Wed, 17 Feb 2021 13:07:22 +0530	[thread overview]
Message-ID: <20210217073725.16656-3-charvi077@gmail.com> (raw)
In-Reply-To: <20210217073725.16656-1-charvi077@gmail.com>

`git commit --fixup=reword:<commit>` creates an empty "amend!" commit
that will reword <commit> without changing its contents when it is
rebased with --autosquash.

Apart from ignoring staged changes it works similarly to
`--fixup=amend:<commit>`.

Example usage:
$ git commit --fixup=reword:HEAD~3
$ git commit --fixup=reword:HEAD~3 -m "new commit message"
