+# NOTE: Any change to formatting may break existing code  which depends
+# upon the previous default formatting. True, nobody likes the
+# default of 0, but it's been there for two decades now and there is
+# probably a LOT of code which expects it. Since the current behavior
+# is not a bug, we really should at least try to census the user community
+# on that before altering it. Not that our test suite is a perfect
+# example of sensitivity to formatting. If we're going to alter it we should
+# simultaneously update the tests and/or test framework to reflect it.
