It's query parameter `SpecialCaseList::Matcher::match(StringRef Query)`

But it needs to be normalized on higher levels, when we know this is path.

Annoying part is that to normalize globs you need to '\' -> '/'.
But to do that you needs some glob parsing to distinguish escape sequence \ and real \ .

And then I don't know which one will be better.



NOTE: There is very simple option, no sure how acceptable.
1. Special list always exact / (for windows and posix)
2. 'query' on windows replace \ to / in file name.

This one must be easy to do.
