The changes added by 39fc408562 (t/t1517: automate `git subcmd -h` tests
outside a repository, 2025-08-08) to automatically loop over all "main"
Git commands will, when run against an installed build using
GIT_TEST_INSTALLED rather than the build in the build directory, include
some extra git-gui commands that are installed by `make install`, or
credential helpers that might be installed manually from the contrib
directories. These fail the test, so record them as such.

Refactor builtin/fmt-merge-msg.c to remove the dependancy on the global
'the_repository'. Remove the 'UNUSED' macro from the 'struct repository'
parameter and replace 'git_config()' with 'repo_config()' so that
configuration is read from the passed repository. Also, add a test to
make sure that "git fmt-merge-msg -h" can be called outside a
repository.

Git experts often check the help summary of a command to make sure they
spell options right when suggesting advice to colleagues. Further, they
might check hidden options when responding to queries about deprecated
options like git-rebase(1)'s "preserve merges" option. But some commands
don't support "--help-all" outside of a git directory. Running (for
example)
git rebase --help-all
outside a directory fails in "setup_git_directory", erroring with the
localized form of
fatal: not a git repository (or any of the parent directories): .git
Like 99caeed05d (Let 'git <command> -h' show usage without a git dir,
2009-11-09), we want to show the "--help-all" output even without a git
dir. Make "--help-all" where we expect "-h" to mean
"setup_git_directory_gently", and interpose early in the natural place
("show_usage_with_options_if_asked").
Do the same for usage callers with show_usage_if_asked.
The exception is merge-recursive, whose help block doesn't use newer
APIs.

t1517 is now focused on testing subcommands outside a repository.
Move the in-repo `-h` test for `prune` to t5304, which covers
this command.

Replace manual `-h` tests with a loop over all subcommands using
`git --list-cmds=main`. This ensures consistent coverage of `-h`
behavior outside a repo and future-proofs the test by covering
new commands automatically.
Known exceptions are skipped or marked as expected failures.

Refactor builtin/prune.c to remove the dependency on the global
'the_repository'. Replace all the occurrences of 'the_repository' with
repo and thus remove the definition '#define
USE_THE_REPOSITORY_VARIABLE'. Also, add a test to make sure that 'git
prune -h' can be called when the repository is `NULL`.

Since we already teach the `repo_config()` in f29f1990 (config:
teach repo_config to allow `repo` to be NULL, 2025-03-08) to allow
`repo` to be NULL, no need to check if `repo` is NULL before calling
`repo_config()`.

Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there
is no longer a need to have that variable declared in all of our tests.
Drop it.

After building Git with NO_LIBCURL, there is no `git remote-http`, so
it's not meaningful to test that it can run outside of a repository.
Indeed, that test will fail. Add the LIBCURL prereq to it.

While most of the commands in Git suite are designed to do useful
things in Git repositories, some commands are also usable outside
any repository. Building on top of an earlier work abece6e9 (t1517:
test commands that are designed to be run outside repository,
2024-05-20) that adds tests for such commands, let's give coverage
to some more commands.
This patch covers commands whose code has hits for
$ git grep setup_git_directory_gently
and passes a pointer to nongit_ok variable it uses to allow it to
run outside a Git repository, but mostly they are tested only to see
that they start up (as opposed to dying with "not in a git
repository" complaint). We may want to update them to actually do
something useful later, but this would at least help us catch
regressions by mistake.

"git apply" can work outside a repository as a better "GNU patch",
but when it does so, it still assumed that it can access
the_hash_algo, which is no longer true in the new world order.
Make sure we explicitly fall back to SHA-1 algorithm for backward
compatibility.
It is of dubious value to make this configurable to other hash
algorithms, as the code does not use the_hash_algo for hashing
purposes when working outside a repository (which is how
the_hash_algo is left to NULL)---it is only used to learn the max
length of the hash when parsing the object names on the "index"
line, but failing to parse the "index" line is not a hard failure,
and the program does not support operations like applying binary
patches and --3way fallback that requires object access outside a
repository.

The git-hash-object(1) command allows users to hash an object even
without a repository. Starting with c8aed5e8da (repository: stop setting
SHA1 as the default object hash, 2024-05-07), this will make us hit an
uninitialized hash function, which subsequently leads to a segfault.
Fix this by falling back to SHA-1 explicitly when running outside of
a Git repository. Users can use GIT_DEFAULT_HASH environment to
specify what hash algorithm they want, so arguably this code should
not be needed.

In c8aed5e8da (repository: stop setting SHA1 as the default object hash,
2024-05-07), we have adapted `initialize_repository()` to no longer set
up a default hash function. As this function is also used to set up
`the_repository`, the consequence is that `the_hash_algo` will now by
default be a `NULL` pointer unless the hash algorithm was configured
properly. This is done as a mechanism to detect cases where we may be
using the wrong hash function by accident.
This change now causes git-patch-id(1) to segfault when it's run outside
of a repository. As this command can read diffs from stdin, it does not
necessarily need a repository, but then relies on `the_hash_algo` to
compute the patch ID itself.
It is somewhat dubious that git-patch-id(1) relies on `the_hash_algo` in
the first place. Quoting its manpage:
A "patch ID" is nothing but a sum of SHA-1 of the file diffs
associated with a patch, with line numbers ignored. As such, it’s
"reasonably stable", but at the same time also reasonably unique,
i.e., two patches that have the same "patch ID" are almost
guaranteed to be the same thing.
We explicitly document patch IDs to be using SHA-1. Furthermore, patch
IDs are supposed to be stable for most of the part. But even with the
same input, the patch IDs will now be different depending on the repo's
configured object hash.
Work around the issue by setting up SHA-1 when there was no startup
repository for now. This is arguably not the correct fix, but for now we
rather want to focus on getting the segfault fixed.

A few commands, like "git apply" and "git patch-id", have been
broken with a recent change to stop setting the default hash
algorithm to SHA-1. Test them and fix them in later commits.
