It is ultimately up to Junio, but I suspect he would be OK if you just
reposted patch 4/7 with the above squashed. Or even just said "I like
this, please squash it into patch 4 (change info messages from
yellow/brown to bold cyan).

As an aside, it made me wonder how hard/useful it would be to color the
snippets even more. Doing this:

diff --git a/t/test-lib-functions.sh b/t/test-lib-functions.sh
index f9ccbf2..3d44a94 100644
--- a/t/test-lib-functions.sh
+++ b/t/test-lib-functions.sh
@@ -364,7 +364,12 @@ test_expect_success () {
 	export test_prereq
 	if ! test_skip "$@"
 	then
-		say >&3 "expecting success: $2"
+		if test -z "$GIT_TEST_HIGHLIGHT"; then
+			say >&3 "expecting success: $2"
+		else
+			say >&3 "expecting success:"
+			echo "$2" | eval "$GIT_TEST_HIGHLIGHT"
+		fi
 		if test_run_ "$2"
 		then
 			test_ok_ "$1"

produces highlighted snippets with:

  GIT_TEST_HIGHLIGHT='highlight -S sh -O ansi'

or

  GIT_TEST_HIGHLIGHT='pygmentize -l sh'

depending on what you have installed on your system. I'm not convinced
it actually adds anything, but it's a fun toy. A real patch would
probably turn it off in non-verbose mode, as invoking the highlighter
(especially pygmentize) repeatedly is somewhat expensive.
