These "expect-failure" tests were not looking for the right string in the patch file. For example: grep "^ *"S. E. Cipient" <scipient@xxxxxxxxxxx>\$" patch5 was looking for "^ *S." in three files: "E." "Cipient <scipient@xxxxxxxxxxx>$" 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.
