[PATCH 12/12] merge-file: run setup_git_directory_gently() sooner

[Jonathan Nieder <jrnieder@gmail.com>]

From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>

Part of a campaign to make repository-local configuration
available early (simplifying the startup sequence for
built-in commands).

As before (except the commit message).

Well, that’s it.  There’s also a separate fix for
"check-ref-format --branch", which I’ll send under separate
cover.

Still to be considered are various commands that currently
do not do an unconditional repository search, especially
low-level commands that are not about the current repository:
verify-pack, mailinfo, hash-object, archive --remote,
check-ref-format, diff --no-index, help, and all the others.
Let’s bite off one thing at a time. :)

Thanks for reading; I hope the patches were not too dull.
Thoughts (especially improvements) welcome, as always.
