[PATCH] t4014: fix arguments to grep

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

These "expect-failure" tests were not looking for the right string
in the patch file.  For example:

	grep "^ *"S. E. Cipient" <scipient@example.com>\$" patch5

was looking for "^ *S." in three files:

    "E."
    "Cipient <scipient@example.com>$"
    patch5

With some implementations of grep, the lack of file "E." was
reported as an error, leading to the expected failure of the test.
With other implementations of grep, the pattern "^ *S." matched what
was in patch5, without missing files diagnosed as an error, which
lead to these tests to unexpectedly pass.
