Summary: os.path.splitext don't handle unix hidden file correctly

Initial Comment:
I expected this.
>>> os.path.splitext('/path/to/.Hiddenfile')
('/path/to/.Hiddenfile', '')

but got this.
>>> os.path.splitext('/path/to/.Hiddenfile')
('/path/to/', '.Hiddenfile')

I hate to be a stick-in-the-mud, but the existing behaviour
is what I would expect, and seems to be regular -- always
picks the last dot:

>>> os.path.splitext('a/b/c/foo.bar')
('a/b/c/foo', '.bar')
>>> os.path.splitext('a/b/c/f.oo.bar')
('a/b/c/f.oo', '.bar')
>>> os.path.splitext('a/b/c/.foo')
('a/b/c/', '.foo')
>>> os.path.splitext('a/b/c/.foo.txt')
('a/b/c/.foo', '.txt')

Changing it would surely break somebody's code too, of course.

Interestingly, altering the behaviour of splitext in such a
way does not contradict the documentation, which is:

"""
Split the pathname path into a pair (root, ext) such that
root + ext == path, and ext is empty or begins with a period
and contains at most one period.
"""

Personally I'm in favour of this change (on Unix it makes
sense, while on Windows you can hardly find an
"extension-only" file).

from test_posixpath.py ::

  self.assertEqual(posixpath.splitext(".ext"), ("", ".ext"))
  
IMHO should then return (".ext",""). if this is desired ::

  if i<=p.rfind('/'):                                                                                   
          return p, ''                                                                                  
  else:                                                                                                
          return p[:i], p[i:]                                                                          

should do
