Comment:

While at it, perhaps also generate a file "PROJ_TOWGS84" since the EPSG
number does not necessarily reflect that (e.g. in Italy with multiple
TOWGS84 parameters for a single code)?

This doesn't seem to work yet or the if() conditions are not fulfilled.

It would also cover the case of creating the Location from the startup
script as well as the location wizard since in Python g.proj is called
from there:

http://grass.osgeo.org/grass71/manuals/libpython/_modules/script/core.html#create_location

Yet the bug in g.proj is to be understood:
{{{
g.proj epsg=4326 location=mylatlong
}}}

--> no PROJ_EPSG generated as expected

I think it's not needed since PROJ_INFO (which includes +towgs84) is
generated always.
