Since Git version v2.29.0, the `git symbolic-ref` command has started
adding extraneous entries to the ref log of the symbolic ref it's
updating.
This change was inadvertently introduced in commit 523fa69c36744ae6
("reflog: cleanse messages in the refs.c layer", 2020-07-10, v2.29.0).
A bug report [1] was made about a failing test in the TopGit test
suite. Further investigations into the cause led to this patch set.
1/2 - adds new tests to monitor this behavior
2/2 - corrects the problem
The tests added in 1/2 are marked `test_expect_failure` and then
changed to `test_expect_success` in 2/2.
