The overall scope of these patches is to replace inappropriate uses of
test_must_fail. IOW, we should only allow test_must_fail to run on `git`
and `test-tool`. Ultimately, we will conclude by making test_must_fail
error out on non-git commands. An advance view of the final series can
be found here[1].

This is the third part. It focuses on t5*.sh.

The first part can be found here[2]. The second part can be found here[3].

Changes since v1:

* Broke up long generate_references() lines for clarity in 2/8

* For-loop &&-chain and renamed variable to "ref" in 2/8

* Cleaned up commit message in 2/8

* Rewrote 4/8 with a simpler test case

    -    t5512: generate references with generate_references()
    +    t5512: stop losing git exit code in here-docs
     
         The expected references are generated using a here-doc with some inline
    -    subshells. If one of the `git rev-parse` invocations within the
    -    subshells failed, its return code is swallowed and we won't know about
    -    it. Replace these here-docs with generate_references(), which actually
    -    reports when `git rev-parse` fails.
    +    command substitutions. If one of the `git rev-parse` invocations within
    +    the command substitutions fails, its return code is swallowed and we
    +    won't know about it. Replace these command substitutions with
    +    generate_references(), which actually reports when `git rev-parse`
    +    fails.
