[MITgcm-support] Generation of broken lines on CS-grid

[Jean-Michel Campin]

Hi Quentin,

I've just updated the utils/matlab/cs_grid/bk_line/ scripts to
enable (by changing ncdf=0 to ncdf=1) to use NetCDF grid-files
instead of plain binary (MDS) files.
But I still have problems (with rdmnc) when each face has several 
tiles in Y dir.

Cheers,
Jean-Michel
