It's unfortunately under-documented, so one would have to work from the 
existing examples in minibuffer.el

The issue was about why the Global project type has to define its own 
find-file generic function.

I haven't actually written any completion styles myself, so Stefan would 
be a better source on the whys and hows of it. But using 
completion-at-point has well-known advantages, so we really want to go

try to work it out as well.
