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.
