I've thought about this too, and I think it would be really hard.

First, there are several files in the picture (eg. /etc/gitconfig,
~/.gitconfig and .git/config), and even included files hence it's not
even a lexical order (file, line).

Then, even if we had a way to order elements with (file, line),
iterating over the hashtable in this order wouldn't be easy (the naive
way, "get the smallest, get the second smallest, ..." would be O(n^2)).
