Gaurav asked me why most of the file names in this directory have a
content_settings_ prefix (despite already being in the content_settings
directory), and I couldn't think of a reason. I told him to be consistent
anyway, but you may want to consider dropping it, so that it's less repetitive.

I think there are other cases where we repeat the subdirectory name in the file
name, like for ipc/. Admittedly that's a far shorter prefix though ;-)
