From user feedback: one user mentioned that "When the <tree-ish> (most
often a commit) is not given" is confusing since it starts with a
negative.
Restructuring so that `git checkout main file.txt` and
`git checkout file.txt` are separate items will help us simplify the
sentence structure a lot.
As a bonus, it appears that `-f` actually only applies to one of those
forms, so we can include fewer options, and now the structure of the
DESCRIPTION matches the SYNOPSIS.

From user feedback: several users say they don't understand the use case
for `--detach`. It's probably not realistic to explain the use case for
detached HEAD state here, but we can improve the situation.
Explain how `git checkout --detach` is different from
`git checkout <branch>` instead of copying over the description from
`git checkout <branch>`, since `git checkout <branch>` will be a
familiar command to many readers.

From user feedback: several users reported having trouble understanding
the difference between `-b` and `-B` ("I think it's because my brain
expects it to contrast with `-b`, but instead it starts off explaining
how they're the same").
Also, in `-B`, 2 users can't tell what the branch is reset *to*.
Simplify the sentence structure in the explanations of `-b` and `-B` and
add a little extra information (what `<start-point>` is, what the branch
is reset to).
Splitting up `-b` and `-B` into separate items helps simplify the
sentence structure since there's less "In this case...".
Replace the long "the branch is not reset/created unless "git checkout"
is successful..." with just "will fail", since we should generally
assume that Git will fail operations in a clean way and not leave
operations half-finished, and that cases where it does not fail cleanly
are the exceptions that the documentation should flag.

From user feedback: several users commented that "Local modifications
to the files in the working tree are kept, so that they can be committed
to the <branch>." didn't seem accurate to them, since
`git checkout <branch>` will often fail.
One user also thought that "... and by pointing HEAD at the branch"
was something that _they_ had to do somehow ("How do I point HEAD at
a branch?") rather than a description of what the `git checkout`
operation is doing for them.
Explain when `git checkout <branch>` will fail and clarify that
"pointing HEAD at the branch" is part of what the command does.
6 users commented that the "You could omit <branch>..." section is
extremely confusing. Explain this in a much more direct way.

There's no need to use the terms "pathspec" or "tree-ish" in the
ARGUMENT DISAMBIGUATION section, which are terms that (from user
feedback on this page) many users do not understand.
"tree-ish" is actually not accurate here: `git checkout` in this case
takes a commit-ish, not a tree-ish. So we can say "branch or commit"
instead of "tree-ish" which is both more accurate and uses more familiar
terms.
And now that the intro to the man pages mentions that `git checkout` has
"two main modes", it makes sense to refer to this disambiguation section
to understand how Git decides which one to use when there's an overlap
in syntax.

From user feedback: in the first paragraph, 5 users reported not
understanding the terms "pathspec" and 1 user reported not understanding
the term "HEAD". Of the users who said they didn't know what "pathspec"
means, 3 said they couldn't understand what the paragraph was trying to
communicate as a result.
One user also commented that "If no pathspec was given..." makes
`git checkout <branch>` sounds like a special edge case, instead of
being one of the most common ways to use this core Git command.
It looks like the goal of this paragraph is to communicate that `git
checkout` has two different modes: one where you switch branches and one
where you just update your working directory files/index. So say that
directly, and use more familiar language (including examples) to say it.

A new subcommand "git repo" gives users a way to grab various
repository characteristics.
* lo/repo-info:
repo: add the --format flag
repo: add the field layout.shallow
repo: add the field layout.bare
repo: add the field references.format
repo: declare the repo command
Remove dependency on the_repository and other globals from the
commit-graph code, and other changes unrelated to de-globaling.

commit-graph: stop passing in redundant repository
commit-graph: stop using `the_repository`
commit-graph: stop using `the_hash_algo`
commit-graph: refactor `parse_commit_graph()` to take a repository
commit-graph: store the hash algorithm instead of its length
commit-graph: stop using `the_hash_algo` via macros
Test clean-up.
* dk/t7005-editor-updates:
t7005: sanitize test environment for subsequent tests
t7005: stop abusing --exec-path
t7005: use modern test style
Doc lint updates to encourage the newer and easier-to-use
`synopsis` format, with fixes to a handful of existing uses.
* ja/doc-lint-sections-and-synopsis:
doc lint: check that synopsis manpages have synopsis inlines
doc:git-for-each-ref: fix styling and typos

"git cmd --help-all" now works outside repositories.
* dk/help-all:
builtin: also setup gently for --help-all
parse-options: refactor flags for usage_with_options_internal
Various options to "git diff" that makes comparison ignore certain
aspects of the differences (like "space changes are ignored",
"differences in lines that match these regular expressions are
ignored") did not work well with "--name-only" and friends.

diff: ensure consistent diff behavior with ignore options
Code clean-up.
* ac/deglobal-fmt-merge-log-config:
builtin/fmt-merge-msg: stop depending on 'the_repository'
environment: remove the global variable 'merge_log_config'
"git diff --no-index" run inside a subdirectory under control of a
Git repository operated at the top of the working tree and stripped
the prefix from the output, and oddballs like "-" (stdin) did not
work correctly because of it. Correct the set-up by undoing what
the set-up sequence did to cwd and prefix.
* jc/diff-no-index-in-subdir:
diff: --no-index should ignore the worktree

t5200: move `update-server-info -h` test from t1517
t/t1517: automate `git subcmd -h` tests outside a repository
"git push" had a code path that led to BUG() but it should have

remote.c: convert if-else ladder to switch
remote.c: remove BUG in show_push_unqualified_ref_name_error()

string_list_split*() family of functions have been extended to
simplify common use cases.

an error, which was incorrect.
* js/rebase-i-allow-drop-on-a-merge:
rebase -i: permit 'drop' of a merge commit
Add the --format flag to git-repo-info. By using this flag, the users
can choose the format for obtaining the data they requested.
Given that this command can be used for generating input for other
applications and for being read by end users, it requires at least two
formats: one for being read by humans and other for being read by
machines. Some other Git commands also have two output formats, notably
git-config which was the inspiration for the two formats that were
chosen here:
- keyvalue, where the retrieved data is printed one per line, using =
for delimiting the key and the value. This is the default format,
targeted for end users.
- nul, where the retrieved data is separated by NUL characters, using
the newline character for delimiting the key and the value. This
format is targeted for being read by machines.

git-repo-info.
The flag `--is-shallow-repository` from git-rev-parse is used for
retrieving whether the repository is shallow. This way, it is used for

Then, add a new field `layout.shallow` to the git-repo-info subcommand
containing that information.

Currently, `git rev-parse` covers a wide range of functionality not
directly related to parsing revisions, as its name suggests. Over time,
many features like parsing datestrings, options, paths, and others
were added to it because there wasn't a more appropriate command
to place them.
Create a new Git command called `repo`. `git repo` will be the main
command for obtaining the information about a repository (such as
metadata and metrics).
Also declare a subcommand for `repo` called `info`. `git repo info`
will bring the functionality of retrieving repository-related
information currently returned by `rev-parse`.
Add the required documentation and build changes to enable usage of
this subcommand.
