Subject: [PATCH] t0001: test git init when run via an alias
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Add some tests to document the correct behavior of (possibly aliased)
init when run within and outside a git directory.

If I set up a simple git alias “quietinit = init --quiet”, usually it
will work just like ‘git init --quiet’.

There are some differences, unfortunately, since in the process of
checking for aliases, git has to look for a .git/config file.  If ‘git
quietinit’ is run from a subdirectory of an existing git repository,
that repository’s configuration will affect the configuration of the
new repository.  In particular, the new repository can inherit
bogus values for core.bare and core.worktree.
