Re: [PATCH] t4200: drop irrelevant code

> While setting up an unresolved merge for `git rerere`, we run `git
> rev-parse` and `git fmt-merge-msg` to create a variable `$fifth` and a
> commit-message file `msg`, which we then never actually use. This has
> been like that since these tests were added in 672d1b789b ("rerere:
> migrate to parse-options API", 2010-08-05). This does exercise `git
> rev-parse` and `git fmt-merge-msg`, but doesn't contribute to testing
> `git rerere`. Drop these lines.
