Well, obviously it's _simpler_ to have the machine-readable format as-is, 
and say "don't try to make it human-readable". But the repo-config patch 
to make it human-readable isn't that hard.

And it's _not_ that hard to make repo-config do the right thing.

Here's a pretty lightly tested patch (on top of my previous one) that does 
exactly that.

(The first part just fixes an indentation bug)
