This seems to say that Windows batch files don't have any special
meaning for single quotes:

http://stackoverflow.com/questions/10737283/single-quotes-and-double-quotes-how-to-have-the-same-behaviour-in-unix-and-wind

Again, is it worth doing something platform-specific?  I can certainly
define a platform-specific macro for " or ' as and use that.  Good idea?
