List of events is cheaper on memory (though I don't think there is
an issue with size of config file), and can be turned into tree
and DOM easily.

So how 'git config --show-origin --list' works?
Ah, I guess it prints as it goes, instead of parsing config file(s)
into stream of events, and printing from those.
