[PATCH v3] ls-files: update test style

["Li Linchao via GitGitGadget" <gitgitgadget@gmail.com>]

From: Li Linchao <lilinchao@oschina.cn>

Update test style in t/t30[*].sh for uniformity, that's to
keep test title the same line with helper function itself,
and fix some indentions.

Add a new section "recommended style" in t/README to
encourage people to use more modern style in test.
