cmd: Fix shortpath handling in for loops.
When 's' is used as a modifier, the paths that are presented to the other modifiers needs to be a short path. Given the 'filename' part of the path may not exist, we cannot use GetShortPathName directly without first removing the filename part to just leave the directory bit.
