I also feel that '-4' is likely to lead to confusion as to whether the
option refers to NFSv4 or IPv4.

How about implementing a '-V n', where 'n' indicates the NFS version
(with '-2' redefined as a deprecated equivalent to '-V 2').  This
leaves '-v' for possible future used as some sort of verbose flag and
both allows explicit specification of NFSv3 (presumably the default
will change from NFSv3 to NFSv4 at some point - by which time we need
a way to request NFSv3) as well as possible future NFS versions (NFSv5
anyone?).

It actually indicates which nfs server to run, not what versions of
nfs is supported, although the experimental one does NFSv4 as well as
NFSv2 and 3.

I'm about to pass a commit that changes the "-4" to "-e" along to my
mentor for approval.

ps: The experimental server does have a way to restrict which versions
    of NFS it supports, via sysctl variables.
