Photo Processing , Gallery and IPTC Data app

[Mark Smith]

Ian, just out of interest, what's the MakeOSXShellPath function for?  
It simply returns it's input with single quotes around it here:

input:    /Users/marksmith/Desktop/370 Manual/370a.jpg
output: '/Users/marksmith/Desktop/370 Manual/370a.jpg'

Best,

Mark
