In the "Sending v2" section, readers are directed to create v2 patches
without using --range-diff. However, it is customary to include a
range-diff against the v1 patches as a reviewer aid.
Update the "Sending v2" section to suggest a simple workflow that uses
the --range-diff option. Also include some explanation for -v2 and
--range-diff to help the reader understand the importance.

c057bad370 (git-cvsserver: use a password file cvsserver pserver,
2010-05-15) adds a way for `git cvsserver` to provide authenticated
pserver accounts without having clear text passwords, but uses the
username instead of the password to the call for crypt(3).
Correct that, and make sure the documentation correctly indicates how
to obtain hashed passwords that could be used to populate this
configuration, as well as correcting the hash that was used for the
tests.
This change will require that any user of this feature updates the
hashes in their configuration, but has the advantage of using a more
similar format than cvs uses, probably also easying any migration.

We've never documented the fact that a client can provide multiple
ref-prefix capabilities. Let's describe the behavior.
We also never discussed the "best effort" nature of the prefixes. The
client side of git.git has always treated them this way, filtering the
result with local patterns. And indeed any client must do this, because
the prefix patterns are not sufficient to express the usual refspecs
(and so for "foo" we ask for "refs/heads/foo", "refs/tags/foo", and so
on).
So this may be considered a change in the spec with respect to client
expectations / requirements, but it's mostly codifying existing
behavior.

While 'git version' is probably the least complex git command,
it is a non-experimental user-facing builtin command. As such
it should have a help page.
Both `git help` and `git version` can be called as options
(`--help`/`--version`) that internally get converted to the
corresponding command. Add a small paragraph to
Documentation/git.txt describing how these two options
interact with each other and link to this help page for the
sub-options that `--version` can take. Well, currently there
is only one sub-option, but that could potentially increase
in future versions of Git.

As was noted in 1a85b49b87a (parse-options: make OPT_ARGUMENT() more
useful, 2019-03-14) there's only ever been one user of the
OPT_ARGUMENT(), that user was added in 20de316e334 (difftool: allow
running outside Git worktrees with --no-index, 2019-03-14).
The OPT_ARGUMENT() feature itself was added way back in
580d5bffdea (parse-options: new option type to treat an option-like
parameter as an argument., 2008-03-02), but as discussed in
1a85b49b87a wasn't used until 20de316e334 in 2019.
Now that the preceding commit has migrated this code over to using
"struct strvec" to manage the "args" member of a "struct
child_process", we can just use that directly instead of relying on
OPT_ARGUMENT.
This has a minor change in behavior in that if we'll pass --no-index
we'll now always pass it as the first argument, before we'd pass it in
whatever position the caller did. Preserving this was the real value
of OPT_ARGUMENT(), but as it turns out we didn't need that either. We
can always inject it as the first argument, the other end will parse
it just the same.
Note that we cannot remove the "out" and "cpidx" members of "struct
parse_opt_ctx_t" added in 580d5bffdea, while they were introduced with
OPT_ARGUMENT() we since used them for other things.

Both Johannes and I assumed (perhaps due to familiarity with rebase)
that am --abort would return the user to a clean state. However, since
am, unlike rebase, is intended to be used within a dirty working tree,
--abort will only clean the files involved in the am operation.

We recently added tips for server admins to configure various transports
to support v2's GIT_PROTOCOL variable. While the protocol-v2 document is
pretty technical and not of interest to most admins, it may be a
starting point for them to figure out how to turn on v2. Let's put some
pointers from there to the other documentation.

The v2 protocol requires that the GIT_PROTOCOL environment variable gets
passed around, but we don't have any documentation describing how this
is supposed to work. In particular, we need to note what server admins
might need to configure to make things work.
The definition of the GIT_PROTOCOL variable is probably the best place
for this, since:
- we deal with multiple transports (ssh, http, etc).
Transport-specific documentation (like the git-http-backend bits
added in the previous commit) are helpful for those transports, but
this gives a broader overview. Plus we do not have a specific
transport endpoint program for ssh, so this is a reasonable place to
mention it.
- the server side of the protocol involves multiple programs. For now,
upload-pack is the only endpoint which uses GIT_PROTOCOL, but that
will likely expand in the future. We're better off with a central
discussion of what the server admin might need to do. However, for
discoverability, this patch adds a pointer from upload-pack's
documentation.

Historically there was a little bit of configuration needed at the
webserver level in order to get the client's v2 protocol probes to Git.
But when we introduced the v2 protocol, we never documented these.
As of the previous commit, this should mostly work out of the box
without any explicit configuration. But it's worth documenting this to
make it clear how we expect it to work, especially in the face of
webservers which don't provide all headers over the CGI interface. Or
anybody who runs across this documentation but has an older version of
Git (or _used_ to have an older version, and wonders why they still have
a SetEnvIf line in their Apache config and whether it's still
necessary).

When changing the scope of a sparse-checkout using cone mode, we might
have some tracked directories go out of scope. The current logic removes
the tracked files from within those directories, but leaves the ignored
files within those directories. This is a bit unexpected to users who
have given input to Git saying they don't need those directories
anymore.
This is something that is new to the cone mode pattern type: the user
has explicitly said "I want these directories and _not_ those
directories." The typical sparse-checkout patterns more generally apply
to "I want files with with these patterns" so it is natural to leave
ignored files as they are. This focus on directories in cone mode
provides us an opportunity to change the behavior.
Leaving these ignored files in the sparse directories makes it
impossible to gain performance benefits in the sparse index. When we
track into these directories, we need to know if the files are ignored
or not, which might depend on the _tracked_ .gitignore file(s) within
the sparse directory. This depends on the indexed version of the file,
so the sparse directory must be expanded.
We must take special care to look for untracked, non-ignored files in
these directories before deleting them. We do not want to delete any
meaningful work that the users were doing in those directories and
perhaps forgot to add and commit before switching sparse-checkout
definitions. Since those untracked files might be code files that
generated ignored build output, also do not delete any ignored files
from these directories in that case. The users can recover their state
by resetting their sparse-checkout definition to include that directory
and continue. Alternatively, they can see the warning that is presented
and delete the directory themselves to regain the performance they
expect.
By deleting the sparse directories when changing scope (or running 'git
sparse-checkout reapply') we regain these performance benefits as if the
repository was in a clean state.
Since these ignored files are frequently build output or helper files
from IDEs, the users should not need the files now that the tracked
files are removed. If the tracked files reappear, then they will have
newer timestamps than the build artifacts, so the artifacts will need to
be regenerated anyway.
Use the sparse-index as a data structure in order to find the sparse
directories that can be safely deleted. Re-expand the index to a full
one if it was full before.
