is_vers4 in mount_libmount.c is based on nfs_umount_is_vers4
in nfsumount.c, except the return values are reversed.
The result of this is:
- a MOUNT_UMNT call is not sent when an NFSv3 or NFSv2
filesystem is unmounted
- a MOUNT_UMNT call *is* sent when and 'nfs4' filesystem
is unmounted (but not when an 'nfs -o vers=4 filesystem
is unmounted, as that is checked elsewhere).
