Subject: [PATCH 3/4] git-gui: fix exception when trying to stage with empty file list
Date: Tue, 9 Jan 2018 15:33:01 +0100 (STD) [thread overview]
Message-ID: <c227a5f8354c736abca92e9b040f7e6f569af119.1515508360.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1515508360.git.johannes.schindelin@gmx.de>
If there is nothing to stage, there is nothing to stage. Let's not try
to, even if the file list contains nothing at all.
This fixes https://github.com/git-for-windows/git/issues/1075
