One thing that is often overlooked is how to allow users to override
a multi-value configuration variable that gets some values from
lower priority configuration files (e.g. ~/.gitconfig) with
repository specific settings in .git/config, and the way we
typically do so is to define "When a variable definition with an
empty string is given, it is a signal to clear everything
accumulated so far."  E.g. if your ~/.gitconfig has

	[push]
		defaultPushOption = foo
		defaultPushOption = bar

and then you write in your .git/config something like

	[push]
		defaultPushOption =
		defaultPushOption = baz

The configuration mechanism reads from lower priority files and then
proceeds to read higher priority files, so the parser would read them
in this order:

	push.defaultPushOption = foo
	push.defaultPushOption = bar
	push.defaultPushOption = 
	push.defaultPushOption = baz

and then it would build a list ('foo'), then ('foo', 'bar'), and
clears it upon seeing an empty, and compute the final result as
('baz').

You may want to do something like that in this code.
