remove use of "tail -n 1" and "tail -1"
The "-n" syntax is not supported by System V versions of tail (which prefer "tail -1"). Unfortunately "tail -1" is not actually POSIX. We had some of both forms in our scripts. Since neither form works everywhere, this patch replaces both with the equivalent sed invocation: sed -ne '$p' Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
