[PATCH 02/17] t0001: replace `cd`+`git` with `git --git-dir` in `check_config`

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

To prepare for `safe.bareRepository` defaulting to `explicit`
(see 8d1a7448206e), replace `cd <dir> && git config` with `git
--git-dir=<dir> config` so the helper does not rely on implicit bare
repository discovery.
