Hi all,

This is mostly a resend of what's currently queued in
"dl/test-must-fail-fixes-5" except with a tiny bit of cleanup on the tip
patch. I'd appreciate a review on this series so that we can finally get
rid of that "Needs review" on the What's Cooking messages ;)


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 fifth part. It focuses on lib-submodule-update.sh and tests
that make use of it.

The first part can be found here[2]. The second part can be found
here[3]. The third part can be found here[4]. The fourth part can be
found here[5].

Changes since v1.2:

* In "lib-submodule-update: pass OVERWRITING_FAIL", use if-then return
  to reduce the amount of code churn
