I've tried to fix test_cmd_line_script but I wasn't able to get all tests
right. Nick, can you please have a look?

  Now in find, rfind, index, and rindex, you can use None as defaults,
  as usual with slicing (both with str and unicode strings).  This
  fixes issue 1259.

  For str only the stringobject.c file was modified.  But for unicode,
  I needed to repeat in the four functions a lot of code, so created
  a new function that does part of the job for them (and placed it in
  find.h, following a suggestion of Barry).

  Also added tests for this behaviour.

  Fix for stupid error (I need to remember to do a full 'make clean + make'
  cycle before the tests...). Sorry.
