The first thing you can do is to run the test with debug and verbose:

debug=t verbose=t ./t7810-grep.sh  
and post the output of these 2 test cases here:
(mine looks like this)

expecting success: 
	echo "ab:a+bc" >expected &&
	git \
		-c grep.patterntype=extended \
		-c grep.patterntype=fixed \
		-c grep.patterntype=basic \
		grep "a+b*c" ab >actual &&
	test_cmp expected actual

ok 142 - grep pattern with grep.patternType=extended, =fixed, =basic

expecting success: 
	echo "ab:abc" >expected &&
	git grep -F -G -E "a+b*c" ab >actual &&
	test_cmp expected actual

ok 143 - grep -F -G -E pattern
