The configuration created by plain --mirror is dangerous and
useless, and we now have --mirror=fetch and --mirror=push to
replace it. Let's warn the user.
One alternative to this is to try to guess which type the
user wants. In a non-bare repository, a fetch mirror doesn't
make much sense, since it would overwrite local commits. But
in a bare repository, you might use either type, or even
both (e.g., if you are acting as an intermediate drop-point
across two disconnected networks).
So rather than try for complex heuristics, let's keep it
simple. The user knows what they're trying to do, so let
them tell us.

git-remote currently has one option, "--mirror", which sets
up mirror configuration which can be used for either
fetching or pushing. It looks like this:
[remote "mirror"]
url = wherever
fetch = +refs/*:refs/*
mirror = true
However, a remote like this can be dangerous and confusing.
Specifically:
1. If you issue the wrong command, it can be devastating.
You are not likely to "push" when you meant to "fetch",
but "git remote update" will try to fetch it, even if
you intended the remote only for pushing. In either
case, the results can be quite destructive. An
unintended push will overwrite or delete remote refs,
and an unintended fetch can overwrite local branches.
2. The tracking setup code can produce confusing results.
The fetch refspec above means that "git checkout -b new
master" will consider refs/heads/master to come from
the remote "mirror", even if you only ever intend to
push to the mirror. It will set up the "new" branch to
track mirror's refs/heads/master.
3. The push code tries to opportunistically update
tracking branches. If you "git push mirror foo:bar",
it will see that we are updating mirror's
refs/heads/bar, which corresponds to our local
refs/heads/bar, and will update our local branch.
To solve this, we split the concept into "push mirrors" and
"fetch mirrors". Push mirrors set only remote.*.mirror,
solving (2) and (3), and making an accidental fetch write
only into FETCH_HEAD. Fetch mirrors set only the fetch
refspec, meaning an accidental push will not force-overwrite
or delete refs on the remote end.
The new syntax is "--mirror=<fetch|push>". For
compatibility, we keep "--mirror" as-is, setting up both
types simultaneously.

'git am --abort' is around for quite a long time now, and users should
normally not poke around inside the .git directory, yet the
documentation of 'git am' still recommends the following:
... if you decide to start over from scratch,
run `rm -f -r .git/rebase-apply` ...
Suggest 'git am --abort' instead.
It's not quite the same as the original, because 'git am --abort' will
restore the original branch, while simply removing '.git/rebase-apply'
won't, but that's rather a thinko in the original wording, because
that won't actually "start over _from scratch_".

The description was unclear if -c or --cc was the default (--cc is for
some commands), and incorrectly implied that the default applies to
all the diff generating commands.
Most importantly, "log" does not default to "--cc" (it defaults to
"--no-merges") and "log -p" obeys the user's wish to see non-combined
format. Only "diff" (during merge and three-blob comparison) and
"show" use --cc as the default.

Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).
When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.
In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.
push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

Here is a 'feature' command for streams to use to require support for
the notemodify (N) command.
When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4,
2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8,
2009-10-09) and it was not obvious it deserved to be a named feature.
But now that is clear, since all major non-git fast-import backends
lack support for it.
Details: on git version with this patch applied, any "feature notes"
command in the features/options section at the beginning of a stream
will be treated as a no-op. On fast-import implementations without
the feature (and older git versions), the command instead errors out
with a message like
This version of fast-import does not support feature notes.
So by declaring use of notes at the beginning of a stream, frontends
can avoid wasting time and other resources when the backend does not
support notes. (This would be especially important for backends that
do not support rewinding history after a botched import.)

The "feature" command allows streams to specify options for the import
that must not be ignored. Logically, they are part of the stream,
even though technically most supported features are synonyms to
command-line options.
Make this more obvious by being more explicit about how the analogy
between most "feature" commands and command-line options works. Treat
the feature (import-marks) that does not fit this analogy separately.

"git diff --cached" (without revision) used to mean "git diff --cached
HEAD" (i.e. the user was too lazy to type HEAD). This "correctly"
failed when there was no commit yet. But was that correctness useful?
This patch changes the definition of what particular command means.
It is a request to show what _would_ be committed without further "git
add". The internal implementation is the same "git diff --cached HEAD"
when HEAD exists, but when there is no commit yet, it compares the index
with an empty tree object to achieve the desired result.

The current treatment of "git reset --keep" emphasizes how it
differs from --hard (treatment of local changes) and how it breaks
down into plumbing (git read-tree -m -u HEAD <commit> followed by git
update-ref HEAD <commit>). This can discourage people from using
it, since it might seem to be a complex or niche option.
Better to emphasize what the --keep flag is intended for --- moving
the index and worktree from one commit to another, like "git checkout"
would --- so the reader can make a more informed decision about the
appropriate situations in which to use it.

The documentation for the post-rewrite hook contains a paragraph from
its early development, where the automatic notes copying facilities
were not part of the series and thus this had to be a hook. Later
versions of the series implemented notes copying as a core feature.
Thus mentioning post-rewrite-copy-notes was never correct. As the
other hooks do not have a "there is no default hook, but..." sentence
unless they ship a sample hook in either templates or contrib, we
simply remove the whole paragraph.
