The options --missing=allow-{any,promisor} were introduced in caf3827e2f
("rev-list: add list-objects filtering support", 2017-11-22) with the
following note in the commit message:
This patch introduces handling of missing objects to help
debugging and development of the "partial clone" mechanism,
and once the mechanism is implemented, for a power user to
perform operations that are missing-object aware without
incurring the cost of checking if a missing link is expected.
The idea that these options are missing-object aware (and thus do not
need to lazily fetch objects, unlike unaware commands that assume that
all objects are present) are assumed in later commits such as 07ef3c6604
("fetch test: use more robust test for filtered objects", 2020-01-15).
However, the current implementations of these options use
has_object_file(), which indeed lazily fetches missing objects. Teach
these implementations not to do so. Also, update the documentation of
these options to be clearer.

Not all man5/man7 guides are mentioned in the 'git(1)' documentation,
which makes the missing ones somewhat hard to find.
Add a list of the guides to git(1) by leveraging the existing
`Documentation/cmd-list.perl` script to generate a file `cmds-guide.txt`
which gets included in git.txt.
Also, do not hard-code the manual section '1'. Instead, use a regex so
that the manual section is discovered from the first line of each
`git*.txt` file.
This addition was hinted at in 1b81d8cb19 (help: use command-list.txt
for the source of guides, 2018-05-20).

Since 1b81d8cb19 (help: use command-list.txt for the source of guides,
2018-05-20), all man5/man7 guides listed in command-list.txt appear in
the output of 'git help -g'.
However, 'git help -g' still prefixes this list with "The common Git
guides are:", which makes one wonder if there are others!
In the same spirit, the man page for 'git help' describes the '--guides'
option as listing 'useful' guides, which is not false per se but can
also be taken to mean that there are other guides that exist but are not
useful.
Instead of 'common' and 'useful', use 'Git concept guides' in both
places. To keep the code in line with this change, rename
help.c::list_common_guides_help to list_guides_help.

The guides 'gitcredentials' and 'gitremote-helpers' do not currently
appear in command-list.txt.
'gitcredentials' was forgotten back when guides were added to
command-list.txt in 1b81d8cb19 (help: use command-list.txt for the
source of guides, 2018-05-20).
'gitremote-helpers' was moved to section 7 in 439cc74632 (docs: move
gitremote-helpers into section 7, 2019-03-25), but command-list.txt was
not updated at the time.
Add these two guides to the list of guides in 'command-list.txt', so
that they appear in the output of 'git help --guides', and capitalize
the first word of the description of 'gitcredentials', as was done in
1b81d8c (help: use command-list.txt for the source of guides,
2018-05-20) for the other guides.
While at it, add a comment in Documentation/Makefile to remind developers
to update command-list.txt if they add a new guide.

When reading the rendered description of `add`, it's easy to trip over
and miss the end of one sentence and the start of the next, making it
seem as if they are part of the same statement, separated only by a
dash:
... specific files such as HEAD, index, etc. - may also be
specified as <commit-ish>; it is synonymous with...
This can be particularly confusing since the thoughts expressed by the
two sentences are unrelated. Reduce the likelihood of confusion by
making it obvious that the two sentences are distinct.

As originally composed, git-worktree.txt employed a mix of "worktree"
and "working tree" which was inconsistent and potentially confusing to
readers. bc483285b7 (Documentation/git-worktree: consistently use term
"linked working tree", 2015-07-20) undertook the task of employing the
term "working tree" consistently throughout the document and avoiding
"worktree" altogether for descriptive text. Since that time, some
instances of "worktree" have crept back in. Continue the work of
bc483285b7 by transforming these to "working tree", as well.

In b79cf959b2 (upload-pack.c: allow banning certain object filter(s),
2020-02-26), we introduced functionality to disallow certain object
filters from being chosen from within 'git upload-pack'. Traditionally,
administrators use this functionality to disallow filters that are known
to perform slowly, for e.g., those that do not have bitmap-level
filtering.
In the past, the '--filter=tree:<n>' was one such filter that does not
have bitmap-level filtering support, and so was likely to be banned by
administrators.
However, in the previous couple of commits, we introduced bitmap-level
filtering for the case when 'n' is equal to '0', i.e., as if we had a
'--filter=tree:none' choice.
While it would be sufficient to simply write
$ git config uploadpackfilter.tree.allow true
(since it would allow all values of 'n'), we would like to be able to
allow this filter for certain values of 'n', i.e., those no greater than
some pre-specified maximum.
In order to do this, introduce a new configuration key, as follows:
$ git config uploadpackfilter.tree.maxDepth <m>
where '<m>' specifies the maximum allowed value of 'n' in the filter
'tree:n'. Administrators who wish to allow for only the value '0' can
write:
$ git config uploadpackfilter.tree.allow true
$ git config uploadpackfilter.tree.maxDepth 0
which allows '--filter=tree:0', but no other values.

Git clients may ask the server for a partial set of objects, where the
set of objects being requested is refined by one or more object filters.
Server administrators can configure 'git upload-pack' to allow or ban
these filters by setting the 'uploadpack.allowFilter' variable to
'true' or 'false', respectively.
However, administrators using bitmaps may wish to allow certain kinds of
object filters, but ban others. Specifically, they may wish to allow
object filters that can be optimized by the use of bitmaps, while
rejecting other object filters which aren't and represent a perceived
performance degradation (as well as an increased load factor on the
server).
Allow configuring 'git upload-pack' to support object filters on a
case-by-case basis by introducing two new configuration variables:
- 'uploadpackfilter.allow'
- 'uploadpackfilter.<kind>.allow'
where '<kind>' may be one of 'blobNone', 'blobLimit', 'tree', and so on.
Setting the second configuration variable for any valid value of
'<kind>' explicitly allows or disallows restricting that kind of object
filter.
If a client requests the object filter <kind> and the respective
configuration value is not set, 'git upload-pack' will default to the
value of 'uploadpackfilter.allow', which itself defaults to 'true' to
maintain backwards compatibility. Note that this differs from
'uploadpack.allowfilter', which controls whether or not the 'filter'
capability is advertised.

In Git 2.28, we stopped special casing 'master' when producing the
default merge message by just removing the code to squelch "into
'master'" at the end of the message.
Introduce multi-valued merge.suppressDest configuration variable
that gives a set of globs to match against the name of the branch
into which the merge is being made, to let users specify for which
branch fmt-merge-msg's output should be shortened. When it is not
set, 'master' is used as the sole value of the variable by default.
The above move mostly reverts the pre-2.28 default in repositories
that have no relevant configuration.
Add a few tests to protect the behaviour with the new configuration
variable from future regression.

Currently we detect the hash algorithm in use by the length of the
object ID. This is inelegant and prevents us from using a different
hash algorithm that is also 256 bits in length.
Since we cannot extend the v2 format in a backward-compatible way, let's
add a v3 format, which is identical, except for the addition of
capabilities, which are prefixed by an at sign. We add "object-format"
as the only capability and reject unknown capabilities, since we do not
have a network connection and therefore cannot negotiate with the other
side.
For compatibility, default to the v2 format for SHA-1 and require v3
for SHA-256.
In t5510, always use format v3 so we can be sure we produce consistent
results across hash algorithms. Since head -n N lists the top N lines
instead of the Nth line, let's run our output through sed to normalize
it and compare it against a fixed value, which will make sure we get
exactly what we're expecting.

The index-pack documentation explicitly states that the pack
name is derived from the sorted list of object names, but
since commit 1190a1acf800 ("pack-objects: name pack files

Be less explicit in the docs as to what the exact output is,
and just say that it's whatever goes into the pack name.
Also update a comment on write_idx_file() since it no longer
modifies the sha1 variable (it's const now anyway), as noted
by Junio.
