Git learned pushing submodules without pushing the superproject by
the user specifying --recurse-submodules=only through 6c656c3fe4
("submodules: add RECURSE_SUBMODULES_ONLY value", 2016-12-20) and
225e8bf778 ("push: add option to push only submodules", 2016-12-20).
For users who use this feature regularly, it is desirable to have an
equivalent configuration.
It turns out that such a configuration (push.recurseSubmodules=only) is
already supported, even though it is neither documented nor mentioned
in the commit messages, due to the way the --recurse-submodules=only
feature was implemented (a function used to parse --recurse-submodules
was updated to support "only", but that same function is used to parse
push.recurseSubmodules too). What is left is to document it and test it,
which is what this commit does.
There is a possible point of confusion when recursing into a submodule
that itself has the push.recurseSubmodules=only configuration, because
if a repository has only its submodules pushed and not itself, its
superproject can never be pushed. Therefore, treat such configurations
as being "on-demand", and print a warning message.

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.

There will be two primary ways to advertise a bundle list: as a list of
packet lines in Git's protocol v2 and as a config file served from a
bundle URI. Both of these fundamentally use a list of key-value pairs.
We will use the same set of key-value pairs across these formats.
Create a new bundle_list_update() method that is currently unusued, but
will be used in the next change. It inspects each key to see if it is
understood and then applies it to the given bundle_list. Here are the
keys that we teach Git to understand:
* bundle.version: This value should be an integer. Git currently
understands only version 1 and will ignore the list if the version is
any other value. This version can be increased in the future if we
need to add new keys that Git should not ignore. We can add new
"heuristic" keys without incrementing the version.
* bundle.mode: This value should be one of "all" or "any". If this
mode is not understood, then Git will ignore the list. This mode
indicates whether Git needs all of the bundle list items to make a
complete view of the content or if any single item is sufficient.
The rest of the keys use a bundle identifier "<id>" as part of the key
name. Keys using the same "<id>" describe a single bundle list item.
* bundle.<id>.uri: This stores the URI of the bundle item. This
currently is expected to be an absolute URI, but will be relaxed to be
a relative URI in the future.
While parsing, return an error if a URI key is repeated, since we can
make that restriction with bundle lists.
Make the git_parse_int() method global so we can parse the integer
version value carefully.

An earlier patch discussed and fixed a scenario where Git could be used
as a vector to exfiltrate sensitive data through a Docker container when
a potential victim clones a suspicious repository with local submodules
that contain symlinks.
That security hole has since been plugged, but a similar one still
exists. Instead of convincing a would-be victim to clone an embedded
submodule via the "file" protocol, an attacker could convince an
individual to clone a repository that has a submodule pointing to a
valid path on the victim's filesystem.
For example, if an individual (with username "foo") has their home
directory ("/home/foo") stored as a Git repository, then an attacker
could exfiltrate data by convincing a victim to clone a malicious
repository containing a submodule pointing at "/home/foo/.git" with
`--recurse-submodules`. Doing so would expose any sensitive contents in
stored in "/home/foo" tracked in Git.
For systems (such as Docker) that consider everything outside of the
immediate top-level working directory containing a Dockerfile as
inaccessible to the container (with the exception of volume mounts, and
so on), this is a violation of trust by exposing unexpected contents in
the working copy.
To mitigate the likelihood of this kind of attack, adjust the "file://"
protocol's default policy to be "user" to prevent commands that execute
without user input (including recursive submodule initialization) from
taking place by default.

Include the "config/grep.txt" file in "git-grep.txt", instead of
repeating an almost identical description of the "grep" configuration
variables in two places.
There is no loss of information here that isn't shown in the addition
to "grep.txt". This change was made by copying the contents of
"git-grep.txt"'s version over the "grep.txt" version. Aside from the
change "grep.txt" being made here the two were identical.
This documentation started being copy/pasted around in
b22520a37c (grep: allow -E and -n to be turned on by default via
configuration, 2011-03-30). After that in e.g. 6453f7b348 (grep: add
grep.fullName config variable, 2014-03-17) they started drifting
apart, with only grep.fullName being described in the command
documentation.

2018-10-27) we gained the include, but didn't do this next step, let's
