I guess you're right. But I tried the script with "exit 0" added at the last 
line and it failed anyway. I added "echo blah" statements to find where it was 
aborting, and it seemed to be at that test statement. When I changed it to an 
if ... fi clause, the problem ceased.

So I don't know why it was doing that.
