Done now in all branches. (r41248-51 reverted)

It's left as is.

I suppose so, but there has been a big change in the datum transform 
philosophy of GDAL and for the moment it is incompatible with GRASS. I 
would imagine keeping things as-is for 6.x, but for 7.x extending g.proj 
to also report the other possible datum transformations from the EPSG 
database (obtained via GDAL) as well as GRASS's own parameters from 
datum.table and datumtransform.table. I think it is necessary to keep the 
internal GRASS lists because (a) the descriptions as to validity seem to 
be more detailed than in the GDAL EPSG list - I need to check that for 
sure but for Monte_Mario at first glance they seemed to be, and (b) there 
is no support for gridshift-based transformations in the EPSG-derived 
list.
