tests: lint for run-away here-doc
We found a few run-away here documents that are started with an
end-of-here-doc marker that is incorrectly spelled, e.g.
git some command >actual &&
cat <<EOF >expect
...
EOF &&
test_cmp expect actual
which ends up slurping the entire remainder of the script as if it
were the data. Often the command that gets misused like this exits
without failure (e.g. "cat" in the above example), which makes the
command appear to work, without ever executing the remainder of the
test.
Piggy-back on the test that catches &&-chain breakage to detect this
case as well.

Maybe we should just warn or die nowadays if this option is in the

index-pack: make pointer-alias fallbacks safer
The final() function accepts a NULL value for certain
parameters, and falls back to writing into a reusable "name"
buffer, and then either:
1. For "keep_name", requiring all uses to do "keep_name ?
keep_name : name.buf". This is awkward, and it's easy
to accidentally look at the maybe-NULL keep_name.
2. For "final_index_name" and "final_pack_name", aliasing
those pointers to the "name" buffer. This is easier to
use, but the aliased pointers become invalid after the
buffer is reused (this isn't a bug now, but it's a
potential pitfall).
One way to make this safer would be to introduce an extra
pointer to do the aliasing, and have its lifetime match the
validity of the "name" buffer. But it's still easy to
accidentally use the wrong name (i.e., to use
"final_pack_name" instead of the aliased pointer).
Instead, let's use three separate buffers that will remain
valid through the function. That makes it safe to alias the
pointers and use them consistently. The extra allocations
shouldn't matter, as this function is not performance
sensitive.

There are two subtleties to note:
- the original called for_each_branch_ref(), etc, in the

For historical reasons, Git searches for the .git/ directory (or the
.git file) by changing the working directory successively to the parent
directory of the current directory, until either anything was found or

Further global state may be changed in case a .git/ directory was found.
We do have a use case, though, where we would like to find the .git/
directory without having any global state touched, though: when we read
the early config e.g. for the pager or for alias expansion.

config code.
Note: the new loop is a *little* tricky, as we have to handle the root
directory specially: we cannot simply strip away the last component
including the slash, as the root directory only has that slash. To remedy
that, we introduce the `min_offset` variable that holds the minimal length
of an absolute path, and using that to special-case the root directory,
including an early exit before trying to find the parent of the root
directory.
