Oh, C'mon Greg... haven't you read my reply to this ?

The trailing slash contains important information which might
otherwise not be regainable or only using explicit queries to
the storage system.

The "/" tells the program that the last path component is
a directory. Removing the slash will also remove that information
from the path (and yes: files without extension are legal).

Now, since e.g. posixpath is also used as basis for fiddling
with URLs and other tools using Unix style paths, removing
the slash will result in problems... just look at what your
browser does when you request http://www.python.org/search ...
the server redirects you to search/ to make sure that the 
links embedded in the page are relative to search/ and not
www.python.org/.

Skip, have you already undone that change in CVS ?
