RFR: JDK-8198569: SetupTextFileProcessing should use sed with 'g'

[Erik Joelsson]

I'm currently trying to use SetupTextFileProcessing with a file where 
the same replacement string appears twice on the same row. This doesn't 
work. To fix it, I would like to add /g on the sed replacement expressions.
