The idea of this helper is that we want to save the current
value of a config variable and then restore it again after
the test completes. However, there's no point in actually
saving the value; it should always be restored to the string
"never" (which you can confirm by instrumenting
save_confirm to print the value it finds).
Let's just replace it with a single test_when_finished call.

These tests are not wrong, but it is much shorter and more
idiomatic to say "verbose" or "test_must_fail" rather than
printing our own messages on failure. Likewise, there is no
need to say "happy" at the end of a test; the test suite
takes care of that.

Since shell loops may drop the exit code of failed commands
inside the loop, some tests try to keep track of the status
by setting a variable. This can end up cumbersome and hard
to read; it is much simpler to just exit directly from the
loop using "return 1" (since each case is either in a helper
function or inside a test snippet).

These are all cases where we do a setup step of the form:
for i in $foo; do
set_up $i || break
done &&
more_setup
would not notice a failure in set_up (because break always
returns a 0 exit code). These are just setup steps that we
do not expect to fail, but it does not hurt to be defensive.
Most can be fixed by converting the "break" to a "return 1"
(since we eval our tests inside a function for just this
purpose). A few of the loops are inside subshells, so we can
use just "exit 1" to break out of the subshell. And a few
can actually be made shorter by just unrolling the loop.

When checking a list of file mtimes, we use a loop and break
out early from the loop if any entry does not match.
However, the exit code of a loop exited via break is always
0, meaning that the test will fail to notice we had a
mismatch. Since the loop is inside a function, we can fix
this by doing an early "return 1".

When we test deleting notes, we run "git notes remove" in a
loop. However, the exit value of the loop will only reflect
the final note we process. We should break out of the loop
with a failing exit code as soon as we see a problem.
Note that we can call "exit 1" here without explicitly
creating a subshell, because the while loop on the
right-hand side of a pipe executes in its own implicit
subshell.
Note also that the "break" above does not suffer the same
problem; it is meant to exit the loop early at a certain
number of iterations. We can bump it into the conditional of
the loop to make this more obvious.

A loop like:
for f in one two; do
something $f ||
break
done
will correctly break out of the loop when we see a failure
of one item, but the resulting exit code will always be
zero. We can fix that by putting the loop into a function or
subshell, but in this case it is simpler still to just
unroll the loop. We do add a helper function, which
hopefully makes the end result even more readable (in
addition to being shorter).

When copying the test repository, we try to detect whether
the copy succeeded. However, most of the heavy lifting is
done inside a for loop, where our "break" will lose the exit
code of the failing "cp". We can take advantage of the fact
that we are in a subshell, and just "exit 1" to break out
with a code.

The expected call sequence is for the caller to use match_pathspec()
repeatedly on a set of pathspecs, accumulating the "hits" in a
separate array, and then call this function to diagnose a pathspec
that never matched anything, as that can indicate a typo from the
command line, e.g. "git commit Maekfile".
Many builtin commands use this function from builtin/ls-files.c,
which is not a very healthy arrangement. ls-files might have been
the first command to feel the need for such a helper, but the need
is shared by everybody who uses the "match and then report" pattern.
Move it to dir.c where match_pathspec() is defined.

`ce` is allocated in make_cache_entry and should be freed if it is not
used any more. refresh_cache_entry as a wrapper around refresh_cache_ent
will either return
- the `ce` given as the parameter, when it was up-to-date;
- a new updated cache entry which is allocated to new memory; or
- a NULL when refreshing failed.
In the latter two cases, the original cache-entry `ce` is not used
and needs to be freed. The rule can be expressed as "if the return
value from refresh is different from the original ce, ce is no
longer used."

Because run_command both spawns and wait()s for the command
before returning control to the caller, any reads from the
pipes we open must necessarily happen after wait() returns.
This can lead to deadlock, as the child process may block
on writing to us while we are blocked waiting for it to
exit.
Worse, it only happens when the child fills the pipe
buffer, which means that the problem may come and go
depending on the platform and the size of the output
produced by the child.
Let's detect and flag this dangerous construct so that we
can catch potential bugs early in the test suite rather than
having them happen in the field.

When we read from a trailer.*.command sub-program, the
current code uses run_command followed by a pipe read, which
can result in deadlock (though in practice you would have to
have a large trailer for this to be a problem). The current
code also leaks the file descriptor for the pipe to the
sub-command.
Instead, let's use capture_command, which makes this simpler
(and we can get rid of our custom helper).

In is_submodule_commit_present, we call run_command followed
by a pipe read, which is prone to deadlock. It is unlikely
to happen in this case, as rev-list should never produce
more than a single line of output, but it does not hurt to
avoid an anti-pattern (and using the helper simplifies the
setup and cleanup).

When we spawn "git submodule status" to read its output, we
use run_command() followed by strbuf_read() read from the
pipe. This can deadlock if the subprocess output is larger
than the system pipe buffer.
Furthermore, if start_command() fails, we'll try to read
from a bogus descriptor (probably "-1" or a descriptor we
just closed, but it is a bad idea for us to make assumptions
about how start_command implements its error handling). And
if start_command succeeds, we leak the file descriptor for
the pipe to the child.
All of these can be solved by using the capture_command
helper.
