We have for some time shown a long warning when the user does not
specify how to reconcile divergent branches with git pull. Make it an
error now.

Carefully excluding t5526, which sees independent development elsewhere
at the time of writing, we use `main` as the default branch name in
t55[23]*. This trick was performed via
$ (cd t &&
sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
-e 's/Master/Main/g' -e 's/naster/nain/g' -- \
t55[23]*.sh &&
git checkout HEAD -- t5526\*)
Note that t5533 contains a variation of the name `master` (`naster`)
that we rename here, too.
This commit allows us to define
`GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for that range of tests.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \
t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
t/t1011-read-tree-sparse-checkout.sh \
t/t1305-config-include.sh t/t1309-early-config.sh \

t/t9302-fast-import-unpack-limit.sh
We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' t/t980[0167]*.sh t/t9811*.sh

If you run fetch but record the result in remote-tracking branches,
and either if you do nothing with the fetched refs (e.g. you are
merely mirroring) or if you always work from the remote-tracking
refs (e.g. you fetch and then merge origin/branchname separately),
you can get away with having no FETCH_HEAD at all.
Teach "git fetch" a command line option "--[no-]write-fetch-head".
The default is to write FETCH_HEAD, and the option is primarily
meant to be used with the "--no-" prefix to override this default,
because there is no matching fetch.writeFetchHEAD configuration
variable to flip the default to off (in which case, the positive
form may become necessary to defeat it).
Note that under "--dry-run" mode, FETCH_HEAD is never written;
otherwise you'd see list of objects in the file that you do not
actually have. Passing `--write-fetch-head` does not force `git
fetch` to write the file.

Often novice Git users forget to say "pull --rebase" and end up with an
unnecessary merge from upstream. What they usually want is either "pull
--rebase" in the simpler cases, or "pull --ff-only" to update the copy
of main integration branches, and rebase their work separately. The
pull.rebase configuration variable exists to help them in the simpler
cases, but there is no mechanism to make these users aware of it.
Issue a warning message when no --[no-]rebase option from the command
line and no pull.rebase configuration variable is given. This will
inconvenience those who never want to "pull --rebase", who haven't had
to do anything special, but the cost of the inconvenience is paid only
once per user, which should be a reasonable cost to help a number of new
users.

This change allows git-merge messages to be cleaned up with the
commit.cleanup configuration or --cleanup option, just like how
git-commit does it.
We also give git-pull the option of --cleanup so that it can also take
advantage of this change.
Finally, add testing to ensure that messages are properly cleaned up.
Note that some newlines that were added to the commit message were
removed so that if a file were read via -F, it would be copied
faithfully.

merge can take --signoff, but without pull passing --signoff down, it
is inconvenient to use; allow 'pull' to take the option and pass it
through.
The order of options in merge-options.txt is mostly alphabetical by
long option since 7c85d274 (Documentation/merge-options.txt: order
options in alphabetical groups, 2009-10-22). The long-option bit
didn't make it into the commit message, but it's under the fold in
[1]. I've put --signoff between --log and --stat to preserve the
alphabetical order.

The previous commit said:
We could add the same option to "git pull" and have it passed
through to underlying "git merge". I do not have a fundamental
opposition against such a feature, but this commit does not do
so and instead leaves it as low-hanging fruit for others,
because such a "two project merge" would be done after fetching
the other project into some location in the working tree of an
existing project and making sure how well they fit together, it
is sufficient to allow a local merge without such an option
pass-through from "git pull" to "git merge".
Prepare a patch to make it a reality, just in case it is needed.

While parsing the command-line arguments, git-pull stops parsing at the
first unrecognized option, assuming that any subsequent options are for
git-fetch, and can thus be kept in the shell's positional parameters
list, so that it can be passed to git-fetch via the expansion of "$@".
However, certain functions in git-pull assume that the positional
parameters do not contain any options:
* error_on_no_merge_candidates() uses the number of positional
parameters to determine which error message to print out, and will
thus print the wrong message if git-fetch's options are passed in as
well.
* the call to get_remote_merge_branch() assumes that the positional
parameters only contains the optional repo and refspecs, and will
thus silently fail if git-fetch's options are passed in as well.
* --dry-run is a valid git-fetch option, but if provided after any
git-fetch options, it is not recognized by git-pull and thus git-pull
will continue to run the merge or rebase.
Fix these bugs by teaching git-pull to parse git-fetch's options as
well. Add tests to prevent regressions.
This removes the limitation where git-fetch's options have to come after
git-merge's and git-rebase's options on the command line. Update the
documentation to reflect this.

Test that when --dry-run is provided to git-pull, it does not make any
changes, namely:
* --dry-run gets passed to git-fetch, so no FETCH_HEAD will be created
and no refs will be fetched.
* The index and work tree will not be modified.

There are quite a lot places where an output file is expected to be
empty, and we fail the test when it is not. The output from running
the test script with -i -v can be helped if we showed the unexpected
contents at that point.
We could of course do
>expected.empty && test_cmp expected.empty actual
but this is commmon enough to be done with a dedicated helper.

git pull passed -q and -v only to git merge, but they can be useful for
git rebase as well, so pass them there, too.
In particular, using -q shuts up the "Already up-to-date." message.
Especially, a new test script runs the same "pull --rebase" twice to
make sure both cases are quiet, when it has something to fetch and
when it is already up to date.

Since "git fetch" learned "--all" and "--multiple" options, it has become
tempting for users to say "git pull --all". Even though it may fetch from
remotes that do not need to be fetched from for merging with the current
branch, it is handy.
"git fetch" however clears the list of fetched branches every time it
contacts a different remote. Unless the current branch is configured to
merge with a branch from a remote that happens to be the last in the list
of remotes that are contacted, "git pull" that fetches from multiple
remotes will not be able to find the branch it should be merging with.
Make "fetch" clear FETCH_HEAD (unless --append is given) and then append
the list of branches fetched to it (even when --append is not given). That
way, "pull" will be able to find the data for the branch being merged in
FETCH_HEAD no matter where the remote appears in the list of remotes to be
contacted by "git fetch".

When running a subfetch, the code propagated some options but not others.
Propagate --force, --update-head-ok and --keep options as well.

All of these tests were bogus, as they created new directory and tried to
run "git pull" without even running "git init" in there. They were mucking
with the repository in $TEST_DIRECTORY.
While fixing it, modernize the style not to chdir around outside of
subshell. Otherwise a failed test will take us to an unexpected directory
and we need to chdir back to the test directory in each test, which is
ugly and error prone.
