Allowed for wildcard paths in multiple platforms in pilfile script

I can't see any reason why this would be win32 only. If anyone knows, please just say.

I reckon it's because POSIX shells will expand unescaped wildcard arguments into a list of matching files before giving them to Python. Windows just passes on the wildcarded argument.

So the Python script needs to expand wildcards for Windows. There's no need to run that on non-Windows.

Yep, looks like you're right. Thanks for pointing that out.
