When cloning a repository without any branches, Git chooses a default
branch name for the as-yet unborn branch.
As part of the implicit initialization of the local repository, Git just
learned to respect `init.defaultBranch` to choose a different initial
branch name. We now really want that branch name to be used as a
fall-back.

There is a growing number of projects and companies desiring to change
the main branch name of their repositories (see e.g.
https://twitter.com/mislav/status/1270388510684598272 for background on
this).
To change that branch name for new repositories, currently the only way
to do that automatically is by copying all of Git's template directory,
then hard-coding the desired default branch name into the `.git/HEAD`
file, and then configuring `init.templateDir` to point to those copied
template files.
To make this process much less cumbersome, let's introduce a new option:
`--initial-branch=<branch-name>`.

When `remote.<name>.branch` is not configured, `git submodule update`
currently falls back to using the branch name `master`. A much better
idea, however, is to use the remote `HEAD`: on all Git servers running
reasonably recent Git versions, the symref `HEAD` points to the main
branch.
Note: t7419 demonstrates that there _might_ be use cases out there that
_expect_ `git submodule update --remote` to update submodules to the
remote `master` branch even if the remote `HEAD` points to another
branch. Arguably, this patch makes the behavior more intuitive, but
there is a slight possibility that this might cause regressions in
obscure setups.
Even so, it should be okay to fix this behavior without anything like a
longer transition period:
- The `git submodule update --remote` command is not really common.
- Current Git's behavior when running this command is outright
confusing, unless the remote repository's current branch _is_ `master`
(in which case the proposed behavior matches the old behavior).
- If a user encounters a regression due to the changed behavior, the fix
is actually trivial: setting `submodule.<name>.branch` to `master`
will reinstate the old behavior.

Commit 6b1db43109 ("clean: teach clean -d to preserve ignored paths",
2017-05-23) added the following code block (among others) to git-clean:
if (remove_directories)
dir.flags |= DIR_SHOW_IGNORED_TOO | DIR_KEEP_UNTRACKED_CONTENTS;
The reason for these flags is well documented in the commit message, but
isn't obvious just from looking at the code. Add some explanations to
the code to make it clearer.
Further, it appears git-2.26 did not correctly handle this combination
of flags from git-clean. With both these flags and without
DIR_SHOW_IGNORED_TOO_MODE_MATCHING set, git is supposed to recurse into
all untracked AND ignored directories. git-2.26.0 clearly was not doing
that. I don't know the full reasons for that or whether git < 2.27.0
had additional unknown bugs because of that misbehavior, because I don't
feel it's worth digging into. As per the huge changes and craziness
documented in commit 8d92fb2927 ("dir: replace exponential algorithm
with a linear one", 2020-04-01), the old algorithm was a mess and was
thrown out. What I can say is that git-2.27.0 correctly recurses into
untracked AND ignored directories with that combination.
However, in clean's case we don't need to recurse into ignored
directories; that is just a waste of time. Thus, when git-2.27.0
started correctly handling those flags, we got a performance regression
report. Rather than relying on other bugs in fill_directory()'s former
logic to provide the behavior of skipping ignored directories, make use
of the DIR_SHOW_IGNORED_TOO_MODE_MATCHING value specifically added in
commit eec0f7f2b7 ("status: add option to show ignored files
differently", 2017-10-30) for this purpose.

dir.h documented quite clearly that DIR_SHOW_IGNORED and

effect by the definition of both enum values. However, a command like
git clean -fx $DIR
would set both values for dir.flags. I _think_ it happened to work
because:
* As dir.h points out, DIR_KEEP_UNTRACKED_CONTENTS only takes effect
if DIR_SHOW_IGNORED_TOO is set.
* As coded, I believe DIR_SHOW_IGNORED would just happen to take
precedence over DIR_SHOW_IGNORED_TOO in the code as currently
constructed.
Which is a long way of saying "we just got lucky".

When git diff is given a symmetric difference A...B, it chooses
some merge base from the two specified commits (as documented).
This fails, however, if there is *no* merge base: instead, you
see the differences between A and B, which is certainly not what
is expected.
Moreover, if additional revisions are specified on the command
line ("git diff A...B C"), the results get a bit weird:
* If there is a symmetric difference merge base, this is used
as the left side of the diff. The last final ref is used as
the right side.
* If there is no merge base, the symmetric status is completely
lost. We will produce a combined diff instead.
Similar weirdness occurs if you use, e.g., "git diff C A...B D".
Likewise, using multiple two-dot ranges, or tossing extra
revision specifiers into the command line with two-dot ranges,
or mixing two and three dot ranges, all produce nonsense.
To avoid all this, add a routine to catch the range cases and
verify that that the arguments make sense. As a side effect,
produce a warning showing *which* merge base is being used when
there are multiple choices; die if there is no merge base.

additional packfiles - this list will be sent to the server. Whenever an
object with one of those OIDs would appear in the packfile transmitted

Whenever a fetch results in a packfile being downloaded, a .keep file is
generated, so that the packfile can be preserved (from, say, a running
"git repack") until refs are written referring to the contents of the
packfile.
In a subsequent patch, a successful fetch using protocol v2 may result
in more than one .keep file being generated. Therefore, teach
fetch_pack() and the transport mechanism to support multiple .keep
files.
Implementation notes:
- builtin/fetch-pack.c normally does not generate .keep files, and thus
is unaffected by this or future changes. However, it has an
undocumented "--lock-pack" feature, used by remote-curl.c when
implementing the "fetch" remote helper command. In keeping with the
remote helper protocol, only one "lock" line will ever be written;
the rest will result in warnings to stderr. However, in practice,
warnings will never be written because the remote-curl.c "fetch" is
only used for protocol v0/v1 (which will not generate multiple .keep
files). (Protocol v2 uses the "stateless-connect" command, not the
"fetch" command.)
- connected.c has an optimization in that connectivity checks on a ref
need not be done if the target object is in a pack known to be
self-contained and connected. If there are multiple packfiles, this
optimization can no longer be done.

"git worktree add" takes special care to avoid creating a new worktree
at a location already registered to an existing worktree even if that
worktree is missing (which can happen, for instance, if the worktree
resides on removable media). "git worktree move", however, is not so
careful when validating the destination location and will happily move
the source worktree atop the location of a missing worktree. This leads
to the anomalous situation of multiple worktrees being associated with
the same path, which is expressly forbidden by design. For example:
$ git clone foo.git
$ cd foo
$ git worktree add ../bar
$ git worktree add ../baz
$ rm -rf ../bar
$ git worktree move ../baz ../bar
$ git worktree list

.../bar beefd00f [baz]
$ git worktree remove ../bar
fatal: validation failed, cannot remove working tree:
'.../bar' does not point back to '.git/worktrees/bar'

same additional validation of the destination directory as done by "git
