absolute before parts read them. This fix was motivated by a test
provoked reading the options before they were absoluticated. 

Added a special check for trying to remove buildout.exe, which fails
on windows and is generally pointless. :)

I'm guessing the behaviour this typo was in is to prevent updating global buildout and setuptools versions?
This could be covered more verbosely...

I hope I haven't changed any intended meaning.

Gotta love PyFlakes

  https://bugs.launchpad.net/zc.buildout/+bug/239212 is indeed solved
  in trunk

- fixed the test for the += -= syntax change.

  attribute '_logger'""" by providing reasonable defaults 
  within the Buildout constructor (related to the new 'allow-hosts' option)
  (patch by Gottfried Ganssauge) (ajung)

- Quote the 'spec' argument, as in the case of installing an egg from
  the buildout-cache, if the filename contains spaces it would fail

AttributeError:
Buildout instance has no attribute '_logger' 

- 1.0.2 release

This change reduces test failures on my current platform from 48 to 3.
I hope it doesn't break zc.buildout on any other platform.
