Yikes, good catch.

I wonder if it would be possible for the test suite to catch this. I
think env--helper would have written a message to stderr, but because we
use --exit-code, we can't tell the difference between that and "false".

I think we'd have go back to something more like:

  test_tristate () {
	bool=$(git env--helper --type=bool --default=true "$1") ||
		eval "error \"$1 is not a bool: \$$1\""
	test "$bool" = "true"
  }
  ...
  if test_tristate GIT_TEST_HTTPD
  then
	... use httpd ...
  fi

Not sure if it's worth it.
