Recently there was a discussion on a similar topic, i.e. to have git
explicitly aware of "default config" as far as "git config -l" etc. go:
https://lore.kernel.org/git/87czvoowg2.fsf@xxxxxxxxxxxxxxxxxxx/
I'd much rather see as add this as some mode of git-config, even if it's
a new --get-or-git-default switch:
git config --get-or-git-default init.defaultBranch
That would just currently die if you fed it any other value than
init.defaultBranch, i.e. that (or similar) would be a generic enough
interface that we could expand on it.
Whereas having a new-built in just for this one config variable...

Should lose the echo, and these comparisons should be using test_cmp,
also use "test_config" not "git config" unless in a sub-repo or similar.
