[GRASS-user] nad grids storage

Hi,
while discussing with S. Turek about r.in.wms coping with french
projection systems, I tested a dataset within grass70. Used to working
with grass64 I store the french nadgrid (ntf_r93.gsb)
in /usr/share/proj/ directory, making a symlink
here: /usr/lib/grass64/etc/nad/
On my local system I noticed for grass70 the grid is taken into account
if stored here:
/usr/local/grass-7.0.svn/etc/proj/nad/

I am wondering :
- if these multiple locations for a single file are necessary;
- if they are correct for each version of grass I use;
- if it is worth adding the french grid to grids provided by default in
grass.

Vincent.
