Message:

A sed regex in gs3-setup.sh was in the wrong format and caused problems that Dr Bainbridge noticed and fixed: the sed regex was trying to get the bitness number by running a File command. It failed as the plus regex operator for one-or-more was not behaving correctly on Mac even with the unexpected escaping in place. Dr Bainbridge got the 2 digits captured with [0-9][0-9] but warned that for 3-digit bitness this would of course break. A stack overflow page reminded how one-or-more can be written as {1,}, but needs escaped braces. It worked with Dr Bainbridge's command line test and should be future proof
