Does'nt _.len or batch_size work ?

if not then DT_In.py (in Zope2/lib/python/DocumentTemplates) reveals the 
following in its doc string - among other things , that should probably
be 
in "real" docs.

  'sequence-step-start-index' -- The index, starting from 0,
             of the start of the current batch.
  'sequence-step-end-index' -- The index, starting from 0, of
             the end of the current batch. 

the size would probably be their difference ;)
