How to .resolve*() and .relativize() Paths which are not issued from the same FileSystem?

I see your point and answering this comes back to how a custom provider 
is suppose to behave when it has distinct FileSystem implementations. I 
need to think about this issue a bit more as changing anything here 
risks creating inconsistencies between resolve/resolveSibling/relativize 
so great care is required. Hopefully get back to you in a few days when 
I find time.
