We are interested in exploring whether gc.cruftPacks=true should become
the default value.
To determine whether it is safe to do so, let's encourage more users to
try it out.
Users who have set feature.experimental=true have already volunteered to
try new and possibly-breaking config changes, so let's try this new
default with that set of users.

In 5b92477f89 (builtin/gc.c: conditionally avoid pruning objects via
loose, 2022-05-20) gc learned to respect '--cruft' and 'gc.cruftPacks'.
'--cruft' is exercised in t5329-pack-objects-cruft.sh, but in a way that
doesn't check whether a lone gc run generates these cruft packs.
'gc.cruftPacks' is never exercised.
Add some tests to exercise these options to gc in the gc test suite.

The Meta/redo-jch.sh script is generated a few lines earlier by running:
$ Meta/Reintegrate master..seen >Meta/redo-jch.sh
But the resulting script is not necessarily executable. Later mentions
of this script invoke it with sh (instead of directly), but this one is
an odd one out.
Update the documentation to invoke the Meta/redo-jch.sh script with sh
in case the maintainer has not made the script executable.

In c847f53712 (Detached HEAD (experimental), 2007-01-01) an error
condition was introduced in rename_branch() to prevent renaming, later
also copying, a detached HEAD.
The condition used was checking for NULL in oldname, the source branch
to rename/copy. That condition cannot be satisfied because if no source
branch is specified, HEAD is going to be used in the call.
The error issued instead is:
fatal: Invalid branch name: 'HEAD'
Let's remove the condition in copy_or_rename_branch() (the current
function name) and check for HEAD before calling it, dying with the
original intended error if we're in a detached HEAD.

During the initial development of the fsck-msgids.txt feature, it
has become apparent that it is very much error prone to make sure
the description in the documentation file are sorted and correctly
match what is in the fsck.h header file.
Add a quick-and-dirty Perl script and doc-lint target to sanity
check that the fsck-msgids.txt is consistent with the error type
list in the fsck.h header file.

The documentation lacks mention of specific <msg-id> that are supported.
While git-help --config will display a list of these options, often
developers' first instinct is to consult the git docs to find valid
config values.

documentation.

The apply code is not prepared to handle extremely large files. It uses
"int" in some places, and "unsigned long" in others.
This combination leads to unfortunate problems when switching between
the two types. Using "int" prevents us from handling large files, since
large offsets will wrap around and spill into small negative values,
which can result in wrong behavior (like accessing the patch buffer with
a negative offset).
Converting from "unsigned long" to "int" also has truncation problems
even on LLP64 platforms where "long" is the same size as "int", since
the former is unsigned but the latter is not.
To avoid potential overflow and truncation issues in `git apply`, apply
similar treatment as in dcd1742e56 (xdiff: reject files larger than
~1GB, 2015-09-24), where the xdiff code was taught to reject large
files for similar reasons.
The maximum size was chosen somewhat arbitrarily, but picking a value
just shy of a gigabyte allows us to double it without overflowing 2^31-1
(after which point our value would wrap around to a negative number).
To give ourselves a bit of extra margin, the maximum patch size is a MiB
smaller than a full GiB, which gives us some slop in case we allocate
"(records + 1) * sizeof(int)" or similar.
Luckily, the security implications of these conversion issues are
relatively uninteresting, because a victim needs to be convinced to
apply a malicious patch.

With the recent turnover on the git-security list, questions came up how
things are usually run. Rather than answering questions individually,
extend Git's existing documentation about security vulnerabilities to
describe the git-security mailing list, how things are run on that list,
and what to expect throughout the process from the time a security bug
is reported all the way to the time when a fix is released.

The last git version that had "diff-tree" in the header text
of "git diff-tree" output was v1.3.0 from 2006. The header text
was changed from "diff-tree" to "commit" in 91539833
("Log message printout cleanups").
Given how long ago this change was made, it is highly unlikely that
anyone is still feeding in outputs from that git version.
Remove the handling of the "diff-tree" prefix and document the
source of the other prefixes so that the overall functionality
is more clear.

There are situations where the user might not want the default
setting where patch-id strips all whitespace. They might be working
in a language where white space is syntactically important, or they
might have CI testing that enforces strict whitespace linting. In
these cases, a whitespace change would result in the patch
fundamentally changing, and thus deserving of a different id.
Add a new mode that is exclusive of --stable and --unstable called
--verbatim. It also corresponds to the config
patchid.verbatim = true. In this mode, the stable algorithm is
used and whitespace is not stripped from the patch text.
Users of --unstable mainly care about compatibility with old git
versions, which unstripping the whitespace would break. Thus there
isn't a usecase for the combination of --verbatim and --unstable,
and we don't expose this so as to not add maintainence burden.
