Summary: enhancing os.chown functionality

Initial Comment:
Hi,
I don't think it is currently possible (with os.chown
or any other Python library function) to change the
groupId of a file without specifying the userId (like
posix 'chgrp' does), or to change the userId without
specifying the groupId.
I would suggest adding the option of having os.chown
accept None as either the userId or groupId, and having
the function change only the 'non-None' portion of the
file ownership.

Thanks for your consideration.

the posix (os) module is intended as a thin wrapper around
operating system services.  The chown(2) syscall requires
that owner and group both be specified.

Possibly an enhanced chownonly/chgrp would find a home in
the 'shutil' module.

Possibly translating a parameter of None into -1 (which
means 'no change') would be accepted as a patch.
