Range misbehaves when step size is 0 or steps over the end value

[GoogleCodeExporter]

What steps will reproduce the problem?
- Call range() with mischievous parameters:
- range(0,1,0)
- range(0,5,3)

What is the expected output? What do you see instead?
- Expect a valid list (maybe empty), instead vm consumes vast amounts of 
memory as very long lists are built (can be an infinite loop until RAM is 
exhausted).

What version of the product are you using? On what operating system?
- r3, Mac OS X / 10.4.11 / PPC.

Please provide any additional information below.
- Patch with unit tests and fix will be appended to this issue.

I merged up to r5, no conflicts.  I added code that will also fix issue #2, 
allowing 
range() to take 1 arg.  Maillist discussion is here:

I grouped my range() unit tests into a function "test_range" in tests.py that 
is called 
by the default build; they all run w/o error.
