description:
Fix sub funciton logic in PyDOLFIN

  >>> v0 = u.sub(0,deepcopy=False)

v0 is a shallowed copied sub function, (deepcopy defaults to False)
and

  >>> v1 = u.sub(0, deepcopy=True)

is a deepcopied version.

The syntax for split is:

   >>> v, p = u.split()
   >>> v, p = u.split(deepcopy=False)
   >>> v, p = u.split(False)

(all equivalent) for two shallow copied sub functions and

   >>> v, p = u.split(deepcopy=True)
   >>> v, p = u.split(True)

(all equivalent) for the deepcopied versions.
