[GRASS-dev] db.connect exit codes

[Hamish]

currently if no DB/driver is defined (new mapset), "db.connect -p" returns
with an error code of 0.

G61> db.connect -p
driver:(null)
database:(null)
schema:(null)
group:(null)
G61> echo $?
0


This makes it hard to test in a script... (v.db.addtable fails)

I assume the (null) comes from printf("%s",..);

Is there anything wrong with setting it to something >0 and ideas on how
to do that?
