Feature #4335: String#split for empty string is always empty array
http://redmine.ruby-lang.org/issues/show/4335

Author: Heesob Park
Status: Open, Priority: Normal
Category: core, Target version: 1.9.x

Here is ruby's behavior:

C:\work>irb
irb(main):001:0> ' '.split('/')
=> [" "]
irb(main):002:0> ''.split('/')
=> []
irb(main):003:0> '/'.split('/')
=> []

Here is python's behavior:
Python 2.4.3 (#1, Jun 11 2009, 14:09:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> ' '.split('/')
[' ']
>>> ''.split('/')
['']
>>> '/'.split('/')
['', '']

Is there any chance of ''.split('/') returns [''] instead of []?
