For example in Index.cs, BuildRelativePathFrom:

if (!normalizedPath.StartsWith(repo.Info.WorkingDirectory, StringComparison.Ordinal))

This isn't accurate when the platform has a filesystem that is case-insensitive but case-preserving. It can reject a path as not being in the repo when it actually is. But I believe this library is supposed to work on Mono as well, so some kind of ability to switch between Ordinal and OrdinalIgnoreCase is probably going to be necessary.

Just thought I would bring it up. Thanks
