false negative with relative back path

[APerricone]

Hello, I have a exception for file not found on a particular case:
I have fileName like '..\filename' and path like 'c:\folder1\folder2', the file 'c:\folder1\filename and the path c:\folder1\folder2 exist, but if I do

trueCase.trueCasePathSync('..\filename' ,'c:\folder1\folder2');

an exception is fired for file not found

I'm not sure this is something we intend to support. Traversing up negates the "safety" added by the second argument as it will have to check that directory; removing the need to do that is the very intent of the second argument (it was introduced to support shared hosting).

Really, the second argument should be thought of less as a "base path" and more of a "known good" path. If there are no permission errors to worry about, trueCasePathSync(path.resolve('c:\folder1\folder2', '..\filename')) would be the preferred usage.
