[PATCH] t0008: make test "set -e" clean

[Junio C Hamano <gitster@pobox.com>]

In order to catch mistakes like misspelling "test_expect_success",
we would like to eventually be able to run our test suite with the
"-e" option on.

A piece of script used "grep" to filter out its input purely for its
output, but of course, "grep" reports with its exit value when it
did not see any hits, which didn't mesh quite well with "set -e".
