[PATCH 09/12] index-pack: run setup_git_directory_gently() sooner

[Jonathan Nieder <jrnieder@gmail.com>]

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

index-pack already runs a repository search unconditionally; running
such a search earlier is not risky and ensures GIT_DIR will be set
correctly if the configuration needs to be accessed from
run_builtin().

Requires the jn/maint-setup-fix topic to apply.  See the cover
letter "[PATCH jn/paginate-fix 0/12] Re: ..." for more on that.

Just like last round, except for the new log message.
