The only way to figure out what JSGME does or doesn't mangle with the "-remove", and when it does it, is to run a LOT of fake files and names through it with a LOT of different letter, number and special character combinations... If I could think like I did when I was a younger man, I might try to make a script to do it, but my brain hurts anymore when I try to think like that...
- it'd be way easier to avoid its use altogether, unfortunately. That leaves a lot of chaff and fluff in the game's files...
