On win32, the following code:

import sys
sys.path.append('../bar/')
import bar

where the file bar.py is present in ../bar/ will return an import error
"No module named bar". Remove the trailing slash and the bar.py is
imported correctly. The problem is identical with backslash. This code
works in Python 2.4.

Not a very serious bug, but it breaks programs working with Python 2.4.
