> 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.
