Bug 17590 - Exporting reports as CSV with 'delimiter' SysPref set to 'tabulation' creates files with 't' as separator

To test:
Set 'delimiter' system preference to 'tabs'
Export a report as csv
Open the file in text editor and note fields separated by character 't'
Apply patch
Export report as CSV
Open file in text editor and note tabs are used to separate fields
