I've updated os.walk() documentation to mention that *dirnames* list
includes symlinks to directories.
To imitate the other two cases:
- treat the symlinks as files:
 for dirpath, dirnames, files in os.walk(top):
 dirs = []
 for name in dirnames:
 (files if islink(join(dirpath, name)) else dirs).append(name)
 dirnames = dirs
- don't include in either of the lists:
 for dirpath, dirnames, files in os.walk(top):
 dirnames[:] = [name for name in dirnames
 if not islink(join(dirpath, name))]
where islink = os.path.islink and join = os.path.join.
I've uploaded the documentation patch. Please, review.
