"git p4" learned four new hooks and also "--no-verify" option to
bypass them (and the existing "p4-pre-submit" hook).
* bk/p4-pre-edit-changelist:
git-p4: add RCS keyword status message
git-p4: add p4 submit hooks
git-p4: restructure code in submit
git-p4: add --no-verify option
git-p4: add p4-pre-submit exit text
git-p4: create new function run_git_hook
git-p4: rewrite prompt to be Windows compatible
Git is an enormously flexible and powerful piece of software. However,
it can be intimidating for many users and there are a set of common
questions that users often ask. While we already have some new user
documentation, it's worth adding a FAQ to address common questions that
users often have. Even though some of this is addressed elsewhere in
the documentation, experience has shown that it is difficult for users
to find, so a centralized location is helpful.
Add such a FAQ and fill it with some common questions and answers.
While there are few entries now, we can expand it in the future to cover
more things as we find new questions that users have. Let's also add
section markers so that people answering questions can directly link
users to the proper answer.
The FAQ also addresses common configuration questions that apply not
only to Git as an independent piece of software but also the ecosystem
of CI tools and hosting providers that people use, since these are the
source of common questions. An attempt has been made to avoid
mentioning any particular provider or tool, but to nevertheless cover
common configurations that apply to a wide variety of such tools.
Note that the long lines for certain questions are required, since
Asciidoctor does not permit broken lines there.

The 'pack.useSparse' configuration variable now defaults to 'true',
enabling an optimization that has been experimental since Git 2.21.
* ds/default-pack-use-sparse-to-true:
pack-objects: flip the use of GIT_TEST_PACK_SPARSE
config: set pack.useSparse=true by default
"git stash" has kept an escape hatch to use the scripted version
for a few releases, which got stale. It has been removed.
* tg/retire-scripted-stash:
stash: remove the stash.useBuiltin setting
stash: get git_stash_config at the top level
SHA-256 transition continues.
* bc/sha-256-part-1-of-4: (22 commits)
fast-import: add options for rewriting submodules
fast-import: add a generic function to iterate over marks
fast-import: make find_marks work on any mark set
fast-import: add helper function for inserting mark object entries
fast-import: permit reading multiple marks files
commit: use expected signature header for SHA-256
worktree: allow repository version 1
init-db: move writing repo version into a function
builtin/init-db: add environment variable for new repo hash
builtin/init-db: allow specifying hash algorithm on command line
setup: allow check_repository_format to read repository format
t/helper: make repository tests hash independent
t/helper: initialize repository if necessary
t/helper/test-dump-split-index: initialize git repository
t6300: make hash algorithm independent
t6300: abstract away SHA-1-specific constants
t: use hash-specific lookup tables to define test constants
repository: require a build flag to use SHA-256
hex: add functions to parse hex object IDs in any algorithm
hex: introduce parsing variants taking hash algorithms
...
A handful of options to configure SSL when talking to proxies have
been added.
* js/https-proxy-config:
http: add environment variable support for HTTPS proxies
http: add client cert support for HTTPS proxies
Via trace2, Git can already log interesting config parameters (see the
trace2_cmd_list_config() function). However, this can grant an
incomplete picture because many config parameters also allow overrides
via environment variables.
To allow for more complete logs, we add a new trace2_cmd_list_env_vars()
function and supporting implementation, modeled after the pre-existing
config param logging implementation.

It turns out that the "--filter=<filter-spec>" option is not
documented anywhere in the "git clone" page, and instead is
detailed carefully in "git rev-list" where it serves a
different purpose.
Add a small bit about this option in the documentation. It
would be worth some time to create a subsection in the "git clone"
documentation about partial clone as a concept and how it can be
a surprising experience. For example, "git checkout" will likely
trigger a pack download.

The pack.useSparse config option was introduced by 3d036eb0
(pack-objects: create pack.useSparse setting, 2019-01-19) and was
first available in v2.21.0. When enabled, the pack-objects process
during 'git push' will use a sparse tree walk when deciding which
trees and blobs to send to the remote. The algorithm was introduced
by d5d2e93 (revision: implement sparse algorithm, 2019-01-16) and
has been in production use by VFS for Git since around that time.
The features.experimental config option also enabled pack.useSparse,
so hopefully that has also increased exposure.
It is worth noting that pack.useSparse has a possibility of
sending more objects across a push, but requires a special
arrangement of exact _copies_ across directories. There is a test
in t5322-pack-objects-sparse.sh that demonstrates this possibility.
This test uses the --sparse option to "git pack-objects" but we
can make it implied by the config value to demonstrate that the
default value has changed.
While updating that test, I noticed that the documentation did not
include an option for --no-sparse, which is now more important than
it was before.
Since the downside is unlikely but the upside is significant, set
the default value of pack.useSparse to true. Remove it from the
set of options implied by features.experimental.

Both "git ls-remote -h" and "git grep -h" give short usage help,
like any other Git subcommand, but it is not unreasonable to expect
that the former would behave the same as "git ls-remote --head"
(there is no other sensible behaviour for the latter). The
documentation has been updated in an attempt to clarify this.
* jc/doc-single-h-is-for-help:
Documentation: clarify that `-h` alone stands for `help`
"git check-ignore" did not work when the given path is explicitly
marked as not ignored with a negative entry in the .gitignore file.
