ncks 4.7.4 not comply with inlin doc on basic case

sorry if wrong place or irrelevent ...

I used since years a script calling "ncks" to extract data with version 4.4.2, and I based my script on the doc ... But with the 4.7.4 delivered by Brew on OSX, my script is not working
anymore, and the example also ...

Ha, yes, I downloaded, compiled and tested the 4.7.4 on Linux too,
with same problem :(

I tried to simplify the bug report and fit with the example on the Web page
http://nco.sourceforge.net/nco.html#ncks-netCDF-Kitchen-Sink
expecially : ncks -C -v three_dmn_var in.nc

for that, I downloaded the test file "in.nc" here :
http://dust.ess.uci.edu/tmp/

for me, OLD is in agreement with the documentation, not NEW !
(and, for me, a code like "ncks" should not change the output on such "basic" case)

OLD $ ncks -C -v three_dmn_var in.nc | head -5
three_dmn_var: type NC_FLOAT, 3 dimensions, 2 attributes, chunked? no, compressed? no, packed? no
three_dmn_var size (RAM) = 234sizeof(NC_FLOAT) = 244 = 96 bytes
three_dmn_var dimension 0: lat, size = 2 NC_FLOAT (Coordinate is lat)
three_dmn_var dimension 1: lev, size = 3 NC_FLOAT (Coordinate is lev)
three_dmn_var dimension 2: lon, size = 4 NC_FLOAT (Coordinate is lon)

NEW: ncks -C -v three_dmn_var in.nc
netcdf in {
dimensions:
lat = 2 ;
lev = 3 ;
lon = 4 ;

variables:
float three_dmn_var(lat,lev,lon) ;
three_dmn_var:long_name = "three dimensional variable with CCM coordinate convention C=[lat,lev,lon], Fortran=(lon,lev,lat)" ;
three_dmn_var:units = "fraction" ;

data:
three_dmn_var =
0, 1, 2, 3,
4, 5, 6, 7,
8, 9, 10, 11,
12, 13, 14, 15,
16, 17, 18, 19,
20, 21, 22, 23 ;
