I am glad you agree.

Probably. But it could potentially make some developer (such as myself,
six months from now) wonder why we don't just remove this call because
clearly nothing uses this on Linux.

So even if it is not quite future-proof from the point of view where we
*technically* would have to extend this comment if we ever introduced
another platform-specific config setting that is relevant to the early
phase of `git init`, I would like to keep the comment in the current form.

Well, actually *almost* in the current form.

I did realize, based on your comment below, that the mention of
`init.templatedir` here is bogus, wrong even: if `git init` is started in
a Git worktree, we do not *want* to use the `init.templatedir` setting
from said worktree.

And that is the reason why...

... we have to call `git_config()` *again* in `create_default_files()`.

Legit.
