A related feature that specifies the maximum length of the history list
uses the `history-length' _property_ of the history list _symbol_
to override the default value of the _variable_ `history-length'
for a particular history list. Exactly the same thing could be
implemented for `history-delete-duplicates', i.e. the property
`history-delete-duplicates' would override its default value
for a particular history list.
