tdf#70806 get rid of the "number 0 for the entire database" nonsense

1. there is no "entire database" in this context
2. 0 was an old workaround for an omitted argument that Excel knows for
   DCOUNT and DCOUNTA functions to count records that match the
   criteria without applying a further count on a selected column, but
   not for other functions
3. Excel does not know a 0 argument
4. ODFF does not specify a 0 argument
=> so give examples that don't use it.
