Also, according to the internet:

write(chainPath(shortDirectory, "A "), "Win32 API strips trailing 
space");
readText(chainPath(shortDirectory, "A")); // Win32 API strips 
trailing space

But:
write(chainPath(longDirectory, "A "), "Win32 API strips trailing 
space");
readText(chainPath(longDirectory, "A")); // File not found

write(chainPath(shortDirectory, "A."));  // fails
write(chainPath(longDirectory, "A."));  // succeeds

This is why we should use the exact same behavior in all cases. 
Always use `\\?\` or never use it.

Since Windows path handling is weird by default, I'd prefer 
always using `\\?\`. It's overhead, but not a huge amount of 
additional overhead compared to filesystem manipulation.
