Please do not overuse/abuse the verb "refactor" like this.  What the
patch does is only reformat---it does not do common "refactoring"
transformations like factoring out common/duplicated code into
helper functions, etc.

If we are doing this step, let's make sure all tests use the modern
style correctly.

In the modern style, we'd write this like so:

	test_expect_success 'initialize test directory' '
		touch -- foo bar baz "space embedded" -q &&
		git add -- foo bar baz "space embedded" -q &&
		git commit -m "add normal files"
	'

In addition to indenting with HT (not SP), two more points are

 - test title comes on the first line;

 - test body is enclosed in a single quote pair, opened on the first
   line and closed on the last line.

This is good.

This has title on the first line, and opening quote of the body as
well, which is the modern style.

We prefer "test ..." over "[ ... ]" (Documentation/CodingGuidelines).

Thanks.
