Subject: Avoid writing to buffer in add_excludes_from_file_1()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the next patch, the buffer that is being used within
add_excludes_from_file_1() comes from another function and does not
have extra space to put \n at the end.
