commit d03090be4f440d70328988e9f792f3bd0ebd956b

    nfsstat -m lists all current nfs mounts, with the mount options.
    It does this by reading /proc/mounts and looking for mounts of type
    "nfs".  It really should check for "nfs4" as well.
    
    For simplicity, just check the first 3 characters of the type.
