Support spaces and parentheses in path

My src directory happens to have spaces and parentheses in it, and that breaks all sorts of things. I ended up symlinking so I could cd into a directory without them, so this isn't a blocking issue, but was a bit annoying.

@markpundsack I am not sure if this is worth the pain. There are obvious places in GDK where adding quotes would help, but the problems with spaces in paths for this sort of thing (Unix software) run deep. I think documenting "don't use spaces in any of your GDK parent directories" might be a better use of everyone's time.

Agreed.
