Err... I see why the exit status might be limited to 255, but not the
output of expr. This is very unfortunate :-(
Does the same limit apply to `expr <number> \* 2'? We don't really
need expr to count the length of the test variable, as long as we can
compute how long it is by doubling at every iteration.
