And to this day we're still barred from creating files or directories named CON, PRN, NUL ... Damn you, IBM

Not just CON but also con.txt, con.js, etc.! Try cloning a git repository with a file called con.js using msysgit. The result is that, when msysgit tries to clone the file, the contents of the file `con.js` are printed to stdout, i.e. to CON.
