Currently the multiselect choice parameter delimits multiple selections with a comma.

I have a situation where I am trying to create a staging/release package from multiple archived builds for use in an automated deployment system. I would like to use the multiselect choice parameter to select locations that the packages are going to be deployed to, and create a path structure with that information.

As I do not want to necessarily create deeply nested folders, it would be nice to either declare the delimiter myself or choose from a small set of directory name safe characters (windows or linux).

I think the comma delimiter should clearly be the default behavior.
