To reproduce, apply the attached patch and run at the project root

	cd t && ./t3700-add.sh --verbose-only=13 --debug --immediate

Relevant part of the output is

	expecting success:
		export GIT_ICASE_PATHSPECS=1 &&
		touch a.if &&
		test_must_fail git add a.?? &&
		! (git ls-files | grep "\\.ig") &&
		(git ls-files | grep a.if)

	fatal: pathspec 'a.ig' did not match any files
	not ok 13 - error out when attempting to add ignored ones but add others
	#
	#               export GIT_ICASE_PATHSPECS=1 &&
	#               touch a.if &&
	#               test_must_fail git add a.?? &&
	#               ! (git ls-files | grep "\\.ig") &&
	#               (git ls-files | grep a.if)

As I understand this, it's a bug.
