Description of problem:
The source seems to indicate (util-linux/mount/nfsmount.c):

                        else if (!strcmp(opt, "nfsvers") ||
                                 !strcmp(opt, "vers"))
                                nfsvers = val;

'vers' and 'nfsvers' are acceptable, since Linux has had to support vers= from the beginning to be compatible with other platforms, and likely always will.  It would be informative if 'vers' was mentioned as usable on the manual page, and folks didn't have to look in the source to find it.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. man 5 nfs


Actual Results:  man 5 nfs currently says about NFS version options:
       nfsvers=n      Use  an  alternate RPC version number to contact the NFS
                      daemon on the remote host.  This option  is  useful  for
                      hosts  that  can  run multiple NFS servers.  The default
                      value is version 2.


Expected Results:  man 5 nfs ought to say about NFS version options:
       nfsvers=n      Use  an  alternate RPC version number to contact the NFS
                      daemon on the remote host.  This option  is  useful  for
                      hosts  that  can  run multiple NFS servers.  The default
                      value is version 2.
       vers=n         vers is an alternative to nfsvers and is compatible with
                      many other operating systems.
