Not only that: setting an environment variable in front of a shell 
function invocation keeps the variable's value in some (most?) shells. 
This occurs frequently in the new code. I don't know whether we have a 
shorter pattern than

	(
		GIT_DIR=../.git &&
		export GIT_DIR &&
		test_stdout "" git -C work rev-parse --show-prefix
	)
