In the preceding commit the use of "test_untraceable=UnfortunatelyYes"
was removed from "t1510-repo-setup.sh" in favor of more narrow
redirections of the output of specific commands (and not entire
sub-shells or functions).
This is in line with the fixes in the series that introduced the
"test_untraceable" facility. See 571e472dc43 (Merge branch
'sg/test-x', 2018-03-14) for the series as a whole, and
e.g. 91538d0cde9 (t5570-git-daemon: don't check the stderr of a
subshell, 2018-02-24) for a commit that's in line with the changes in
the preceding commit.
We've thus solved the TODO item noted when "test_untraceable" was
added to "t1510-repo-setup.sh" in 58275069288 (t1510-repo-setup: mark
as untraceable with '-x', 2018-02-24).
So let's remove the feature entirely. Not only is it currently unused,
but it actively encourages an anti-pattern in our tests. We should be
testing the output of specific commands, not entire subshells or
functions.
That the "-x" output had to be disabled as a result is only one
symptom, but even under bash those tests will be harder to debug as
the subsequent check of the redirected file will be far removed from
the command that emitted the output.
