Yeah, sorry. But you got the point.

So you want "git-repo-config --dump" to output something which has to be 
scanned for escaping sequences?

If you call

	$ git repo-config -l

you will _no longer_ see "\n"s, but rather newlines.

I don't know why you insist on newlines, when a NUL makes perfect sense: 
Take everything until the next NUL. This is the key. Then take everything 
until the next NUL. This is the value. Repeat until EOF.

Yes, it returns "", but this is _wrong_. A single "[section] noval" _only_ 
makes sense as a boolean. The information lies in its _presence_, which is 
as good as saying "true".
