Paul demonstrates the shortcoming of commonprefix:

But it doesn't handle the fact that Windows paths are case-insensitive, or that Posix paths can have symlinks... or that one path might be relative and another absolute...

As soon as you move away from being a string operation, you get an endless series of gotchas... none of which are currently documented.
