+As this comes up every now and then, and rather should be documented in an
+extra list of the Help system, functions that support Wildcards or Regular
+Expressions *and* depend on the setting under
+Tools -> Options -> Calc -> Calculate are those that in ODF OpenFormula (ODFF)
+are defined to depend on the HOST-USE-REGULAR-EXPRESSIONS or HOST-USE-WILDCARDS
