* Modules/bz2module.c
  (BZ2FileObject): Now the structure includes a pointer to a file object,
   instead of "inheriting" one. Also, some members were copied from the
   PyFileObject structure to avoid dealing with the internals of that
   structure from outside fileobject.c.

  (Util_GetLine,Util_DropReadAhead,Util_ReadAhead,Util_ReadAheadGetLineSkip,
   BZ2File_write,BZ2File_writelines,BZ2File_init,BZ2File_dealloc,
   BZ2Comp_dealloc,BZ2Decomp_dealloc):
   	These functions were adapted to the change above.

  (BZ2File_seek,BZ2File_close): Use PyObject_CallMethod instead of
   getting the function attribute locally.

  (BZ2File_notsup): Removed, since it's not necessary anymore to overload
   truncate(), and readinto() with dummy functions.

  (BZ2File_methods): Added xreadlines() as an alias to BZ2File_getiter,
   and removed truncate() and readinto().

  (BZ2File_get_newlines,BZ2File_get_closed,BZ2File_get_mode,BZ2File_get_name,
   BZ2File_getset):
   	Implemented getters for "newlines", "mode", and "name".

  (BZ2File_members): Implemented "softspace" member.

  (BZ2File_init): Reworked to create a file instance instead of initializing
   itself as a file subclass. Also, pass "name" object untouched to the
   file constructor, and use PyObject_CallFunction instead of building the
   argument tuple locally.

  (BZ2File_Type): Set tp_new to PyType_GenericNew, tp_members to
   BZ2File_members, and tp_getset to BZ2File_getset.

  (initbz2): Do not set BZ2File_Type.tp_base nor BZ2File_Type.tp_new.


* Doc/lib/libbz2.tex
  Do not mention that BZ2File inherits from the file type.

  Fixed minor typo, suggested by Drew Perttula <drewp@bigasterisk.com>.

iteration support was documented; the docs for __iter__() were just
confusing.
