Subject: [PATCH] difftool: silence warning
Date: Tue, 21 Aug 2012 08:59:18 +0200	[thread overview]
Message-ID: <1345532358-11742-1-git-send-email-rosslagerwall@gmail.com> (raw)

Silence a warning given when running git difftool --dir-diff and
there are no changes.
This is because command_oneline returns undef when the command has no
output, not ''.
