Summary: extending os.walk to support following symlinks

Initial Comment:
this is a very simple extension to os.walk to optionally walk down 
into symlink directories, when it is supported by the operating 
system. This patch keeps a compatible interface by having this 
option disabled.

I'm not sure if this is a good idea; although I am certain it would be
useful at times. Dangerous! But if its documented, ... and there's our
problem :)

Patch applies cleanly to the HEAD, but needs documentation.

The docs to os.walk say:
"""
Note: On systems that support symbolic links, links to
subdirectories appear in dirnames lists, but walk() will not
visit them (infinite loops are hard to avoid when following
symbolic links). To visit linked directories, you can
identify them with os.path.islink(path), and invoke
walk(path) on each directly.
"""

Nevertheless, we could offer this option with a caution message.
