> The chown and chgrp commands enforce a check on a valid set of characters for 
> user and group.  The set of valid characters does not include space.  On some 
> platforms (notably Windows), the space character is acceptable.  We've seen 
> this cause test failures in {{TestFsShellReturnCode}} when running on Windows 
> if the logged-in user is a member of a group like Remote Desktop Users.
