+While uid_t and gid_t are both unsigned, the values (uid_t) -1 and
+(gid_t) -1 are reserved.  A uid or gid argument of -1 to the chown(2)
+system call means to leave the uid/gid unchanged.  Catch this case
+so that trying to set a uid or gid to -1 will result in an error.

+Test cases:

+  chown 4294967295 file
+  chown :4294967295 file
+  chgrp 4294967295 file
