Ah, but this is unfortunate, it still doesn't work. Since it should still
be possible to include " signs in a raw string, they are in fact escaped
(the \-es are left in the string). Printing r"\"" prints \".
So raw strings can never end in an odd number of backslashes... Newbies
shouldn't have to deal with this stuff.

"C:\\" Does work. So does r"C:\ " (with a space).

Also, you can use / inside a path. "C:/Program Files/etc" is a completely
legal Windows path, it can use both. It looks unusual though.
