Fixes #1048. It took some time to get it right, but I'm pretty sure this covers every possible illegal file name now.

For reference, the following names are illegal on Windows:

A name with any of the characters < > : " \ | ? * or any characters in the ASCII range 0-31
CON, PRN, AUX, NUL, COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, COM¹, COM², COM³, LPT0, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, LPT¹, LPT², and LPT³
A name ending with a space or period
