Side-step line-ending corruption leading to t3032 failures.

By default, MSYS grep and sed throw away CR from CRLF line-endings.
Tests t3032.4 through t3032.8 employ grep and fail due to this behavior.
Test t3032.9 employs sed and fails. Fix by employing grep's -U/--binary
and sed's -b/--binary switches to suppress the default behavior of
dropping CR characters.
