I see my depot having:

     |   #(  "for"
             #(FOR_INIT ((variableDef)+ | elist)?)
             #(FOR_CONDITION (expression)?)
             #(FOR_ITERATOR (elist)?)
             stat
         )

like yours, but with (...)+.  I suspect that I fixed this after 2.7.2 
:) ;)

Thanks,
Terence
