3ac8f6301e t55[23]*: adjust the references to the default branch name "main"
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.

334afbc76f tests: mark tests relying on the current default for init.defaultBranch
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/t7508-status.sh t/t7606-merge-custom.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

3b5bf96573 t, doc: update tests, reference for "--force-if-includes"
Update test cases for the new option, and document its usage
and update related references.

Update test cases for the new option, and document its usage
and update related references.

 - t/t5533-push-cas.sh:
   Update test cases for "compare-and-swap" when used along with
   "--force-if-includes" helps mitigate overwrites when remote
   refs are updated in the background; allows forced updates when
   changes from remote are integrated locally.

 - Documentation:
   Add reference for the new option, configuration setting
   ("push.useForceIfIncludes") and advise messages.

d3c6751b18 tests: make use of the test_must_be_empty function
Change various tests that use an idiom of the form:

    >expect &&
    test_cmp expect actual

To instead use:

    test_must_be_empty actual

The test_must_be_empty() wrapper was introduced in ca8d148daf ("test:
test_must_be_empty helper", 2013-06-09). Many of these tests have been
added after that time. This was mostly found with, and manually pruned
from:

    git grep '^\s+>.*expect.* &&$' t

f17d642d3b push: document & test --force-with-lease with multiple remotes
Document & test for cases where there are two remotes pointing to the
same URL, and a background fetch & subsequent `git push
--force-with-lease` shouldn't clobber un-updated references we haven't
fetched.

Some editors like Microsoft's VSC have a feature to auto-fetch in the
background, this bypasses the protections offered by
--force-with-lease & --force-with-lease=<refname>, as noted in the
documentation being added here.

See the 'Tools that do an automatic fetch defeat "git push
--force-with-lease"' (<1491617750.2149.10.camel@mattmccutchen.net>)
git mailing list thread for more details. Jakub Narębski suggested
this method of adding another remote to bypass this edge case,
document that & add a test for it.

9eed4f3711 t5533: make it pass on case-sensitive filesystems
The newly-added test case wants to commit a file "c.t" (note the lower
case) when a previous test case already committed a file "C.t". This
confuses Git to the point that it thinks "c.t" was not staged when "git
add c.t" was called.

Simply make the naming of the test commits consistent with the previous
test cases: use upper-case, and advance in the alphabet.

This came up in local work to rebase the Windows-specific patches to the
current `next` branch. An identical fix was suggested by John Keeping.

64ac39af70 push: allow pushing new branches with --force-with-lease
If there is no upstream information for a branch, it is likely that it
is newly created and can safely be pushed under the normal fast-forward
rules.  Relax the --force-with-lease check so that we do not reject
these branches immediately but rather attempt to push them as new
branches, using the null SHA-1 as the expected value.

In fact, it is already possible to push new branches using the explicit
--force-with-lease=<branch>:<expect> syntax, so all we do here is make
this behaviour the default if no explicit "expect" value is specified.

eee98e74f9 push: add shorthand for --force-with-lease branch creation
Allow the empty string to stand in for the null SHA-1 when pushing a new
branch, like we do when deleting branches.

This means that the following command ensures that `new-branch` is
created on the remote (that is, is must not already exist):

	git push --force-with-lease=new-branch: origin new-branch

b2e93f88cb push: fix ref status reporting for --force-with-lease
The --force--with-lease push option leads to less
detailed status information than --force. In particular,
the output indicates that a reference was fast-forwarded,
even when it was force-updated.

Modify the --force-with-lease ref status logic to leverage
the --force ref status logic when the "lease" conditions
are met.

Also, enhance tests to validate output status reporting.

53350a35a3 t: avoid using ":" for comments
The ":" is not a comment marker, but rather a noop command.
Using it as a comment like:

  : do something
  cmd1 &&

  : something else
  cmd2

breaks the &&-chain, and we would fail to notice if "cmd1"
failed in this instance. We can just use regular "#"
comments instead.

99094a7ad4 t: fix trivial &&-chain breakage
These are tests which are missing a link in their &&-chain,
but during a setup phase. We may fail to notice failure in
commands that build the test environment, but these are
typically not expected to fail at all (but it's still good
to double-check that our test environment is what we
expect).
