Ouch. Ok, yea, this is pretty solid evidence that ALL usage of 
non-`\\?\` paths on Windows needs to be killed dead, dead, dead.

If it were decided (not that I'm in favor of it) that we should be 
protecting developers from files named " a ", "a." and "COM1", then that 
really needs to be done on our end on top of mandatory `\\?\`-based 
access. Anyone masochistic enough to really WANT to deal with MAX_PATH 
and such is free to access the Win32 APIs directly.
