Um... the best I can say then is -0 in the hope that we can find a 
better delimiter or syntax. Unfortunately I just can't come up with a 
better option at the moment.

Unfortunately "@driver=ingres,dbname=test.tif" is also a valid filename, 
so we'd have the same problem as with "HFA:test.tif" above.

I also think it is important to be consistent between GDAL and OGR for 
something like this.

Once again, I'm not trying to kill the idea, just pointing the flaws in 
the hope that the someone in the group will find a more predictable 
mechanism.
