Subject: [PATCH 2/7] built-in add -p: implement the "stash" and "reset" patch modes
Date: Tue, 17 Dec 2019 10:40:59 +0000	[thread overview]
Message-ID: <846cf16e77f4af39310902129be40fda664ace72.1576579264.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.174.git.1576579264.gitgitgadget@gmail.com>

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The `git stash` and `git reset` commands support a `--patch` option, and
both simply hand off to `git add -p` to perform that work. Let's teach
the built-in version of that command to be able to perform that work, too.
