We are using `test_must_fail $command`. However, $command is not
necessarily a git command; it could be a test helper function.
In an effort to stop using test_must_fail with non-git commands, instead
of invoking `test_must_fail $command`, run
`OVERWRITING_FAIL=test_must_fail $command` instead in
test_submodule_switch_common().
In the case where $command is a git command,
test_submodule_switch_common() is called by one of
test_submodule_switch() or test_submodule_forced_switch(). In those two
functions, pass $command like this:
test_submodule_switch_common "eval \$OVERWRITING_FAIL git $command"
When $command is a helper function, the parent function calling
test_submodule_switch_common() is test_submodule_switch_func(). For all
test_submodule_switch_func() invocations, increase the granularity of
the argument test helper function by prefixing the git invocation which is
meant to fail with $OVERWRITING_FAIL like this:
$OVERWRITING_FAIL git checkout "$1"
This is useful because currently, when we run a test helper function, we
just mark the whole thing as `test_must_fail`. However, it's possible
that the helper function might fail earlier or later than expected due
to an introduced bug. If this happens, then the test case will still
report as passing but it should really be marked as failing since it
didn't actually display the intended behaviour.
While we're at it, some helper functions have git commands piping into
another git command. Break these pipes up into two separate invocations
with a file buffer so that the return code of the first command is not
lost.
