That's where I am unsure.  Is the initdb-safe and backup advantages
enough to start to migrate those out to data/?  I need to hear
comments on that.

One new idea is to move the config files into data/etc.  That makes it
clear which are config files, and makes backup a little easier.  It
would make -C more logical because you are not moving a clear directory.
