Hmm...

Just a style thing, but it is easier to read to write:

        test_expect_success 'set up basic repos' '
                >foo &&
                >bar &&
                ...
        '

I would really prefer to see a test that checks output with real contents,
not just "switch to color".  E.g. --format="Title: %C${color}%s%C(normal)"
or something like that.

Also you probably would want to make this one round into a shell function
e.g.

	make_expected ()
        {
        	git config --get-color no.such.slot "$1"
	}

	run_format_test ()
        {
		flag=$1 color=$2
                test_expect_success "%C$color with ..." '
			make_expected $color >expected
                        git config color.ui $flag &&
                        git log -1 --pretty=format:'%C($color)' >actual &&
                        test_cmp expected actual"
                '
                ...
	}

and then run this loop:

	for flag in flase true always
        do
        	for color in red green blue reset
                do
                	run_format_test $flag $color
		done
	done
