File names with spaces and command line utility

I have a command line utility which takes a list of files, and runs some processing. Since it's simply iterating over argv, it's absolutely necessary to quote the file names coming in -- some of the names contain spaces. Simply drawing a connector between the asset group and the XnaExec task doesn't do that, so I'm wondering how I can make something (an intermediate task maybe?) that quotes all the files.
