Further to my original post, I have since found that the problem is
not associated with the brackets around the expression but is
related to the execution of test.

If the file is present, the condition is met and the statements are
executed.

If the file is zero length, the condition is not true, then
the sequence of commands are not executed but the if statement
is not terminated.

And ideas on why this bizarre behavior and how to get it to
work properly?
