[PATCH 1/2] t8005: avoid grep on non-ASCII data

[John Keeping]

GNU grep 2.23 detects the input used in this test as binary data so it
does not work for extracting lines from a file.  We could add the "-a"
option to force grep to treat the input as text, but not all
implementations support that.  Instead, use sed to extract the desired
lines since it will always treat its input as text.

While touching these lines, modernize the test style to avoid hiding the
exit status of "git blame" and remove a space following a redirection
operator.
