"git receive-pack" used to use all the local refs as the boundary for
checking connectivity of the data "git push" sent, but now it uses
only the refs that it advertised to the pusher. In a repository with
the .hideRefs configuration, this reduces the resources needed to
perform the check.

Add a new `--exclude-hidden=` option that is similar to the one we just
added to git-rev-list(1). Given a section name `uploadpack` or `receive`
as argument, it causes us to exclude all references that would be hidden
by the respective `$section.hideRefs` configuration.

Users can optionally hide refs from remote users in git-upload-pack(1),
git-receive-pack(1) and others via the `transfer.hideRefs`, but there is
not an easy way to obtain the list of all visible or hidden refs right
now. We'll require just that though for a performance improvement in our
connectivity check.
Add a new option `--exclude-hidden=` that excludes any hidden refs from
the next pseudo-ref like `--all` or `--branches`.

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.

Previously, the example *decreased* the cache timeout compared to the
default, making it less user friendly.
Instead, nudge users to make cache more usable. Many users choose
store over cache.

Once upon a time, Matheus wrote some patches to make
git grep [--cached | <REVISION>] ...
restrict its output to the sparsity specification when working in a
sparse checkout[1]. That effort got derailed by two things:
(1) The --sparse-index work just beginning which we wanted to avoid
creating conflicts for
(2) Never deciding on flag and config names and planned high level
behavior for all commands.
More recently, Shaoxuan implemented a more limited form of Matheus'
patches that only affected --cached, using a different flag name,
but also changing the default behavior in line with what Matheus did.
This again highlighted the fact that we never decided on command line
flag names, config option names, and the big picture path forward.
The --sparse-index work has been mostly complete (or at least released
into production even if some small edges remain) for quite some time
now. We have also had several discussions on flag and config names,
though we never came to solid conclusions. Stolee once upon a time
suggested putting all these into some document in
Documentation/technical[3], which Victoria recently also requested[4].
I'm behind the times, but here's a patch attempting to finally do that.

In a similar spirit as the previous commit, the 'seen' branch gets
rebuilt by reintegrating topics between 'jch' and the (old) tip of
'seen'.
Update the instructions on how to generate Meta/redo-seen.sh for the
first time to reflect this.
Signed-off-by: Taylor Blau <me@ttaylorr.com>
Rebuilding the 'jch' branch begins by reintegrating any topics between
'master' and 'jch', not 'master' and 'seen'.
In the maintainer guide, the documentation isn't quite right, since the
initial input to Meta/Reintegrate is "master..seen", not "master..jch".
This can lead to confusing results when generating the Meta/redo-jch.sh
script for the first time.
Additionally, rebuilding 'jch' takes place in two steps. First, running
the script up to the first "### match next" cut-line, and then comparing
the result with what's on 'next' (i.e. with "git diff jch next"). Then,
the remaining set of topics get merged down to 'jch' (which aren't on
'next') by running the entire "redo-jch.sh" script.
Clarify the documentation to reflect this.

Git has an additional "commit graph" capability that supplements the
normal commit object's directed acyclic graph (DAG). The supplemental
commit graph file is designed for speed of access.
Describe the commit graph both from the normative DAG view point and
from the commit graph file perspective.
Also, clarify the link between the branch ref and branch tip
by linking to the `ref` glossary entry, matching this commit graph
entry.

Subsequent commit catches the few cases where the hyphenation of
commit-graph was missing.
