Subject: [PATCH 1/3] tools/parse-options: Add '\n' at the end of error messages
Date:   Mon,  9 Apr 2018 16:36:31 +0530
In-Reply-To: <20180409110633.20767-1-ravi.bangoria@linux.vnet.ibm.com>
References: <20180409110633.20767-1-ravi.bangoria@linux.vnet.ibm.com>
Message-Id: <20180409110633.20767-2-ravi.bangoria@linux.vnet.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Few error messages does not have '\n' at the end and thus next
prompt gets printed in the same line. Ex,

  linux~$ perf buildid-cache -verbose --add ./a.out
   Error: did you mean `--verbose` (with two dashes ?)linux~$

Fix it.
