[PATCH 12/12] t0001: drop subshells just for "cd"

[Jeff King <peff@xxxxxxxx>]

Many tests do something like:

  (
	mkdir foo &&
	cd foo &&
	git init
  )

You can do the same these days with "git init foo", which
makes the tests shorter and simpler to read.

Unlike the last patch, this one _could_ have an affect. I made the
assumption that "git init foo" would behave sanely, but that other
complex things should be left alone. E.g., ones that set GIT_DIR in the
environment to a relative path might be affected based on when git does
the "chdir".
