Sure, but why? Strings generally get emitted with quotes around them, I 
don't see a good reason for filenames to be different, especially if it 
makes the output easier to parse.

The way I see it, spaces in filenames are regrettably somewhat common. 
Backslashes and quotes rather less so, to the point I really don't see a 
need to worry about them at the moment, and the necessary quoting could 
be added later if really necessary.
