The :foo marshallers are inconsistent with empty values:
  <input type="hidden" name="emptylist:list" value="" /> 
  <input type="hidden" name="emptylines:lines" value="" /> 
  <input type="hidden" name="emptytuple:tuple" value="" />
  <input type="hidden" name="emptytokens:tokens" value="" />

Sumbitting a form like this gives you:
 emptytuple	('',)
 emptytokens	[]
 emptylist	['']
 emptylines	['']

Also as of zope 2.8.4-final I get
 emptylines []
 emptytokens        []
 emptytuple ('',)
 emptylist  ['']

This seems quite odd; the :tokens marshaller has the correct behavior but it seems more desireable to  return empty tuples or lists for the others.  It also might be nice to inculde a :default for these options similar to :records.
