"git diff" learned a variant of the "--patience" algorithm, to
which the user can specify which 'unique' line to be used as
anchoring points.
* jt/diff-anchored-patience:
diff: support anchoring line(s)
Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])
When describing commits, we try to anchor them to tags or refs, as these
are conceptually on a higher level than the commit. And if there is no ref
or tag that matches exactly, we're out of luck. So we employ a heuristic
to make up a name for the commit. These names are ambiguous, there might
be different tags or refs to anchor to, and there might be different
path in the DAG to travel to arrive at the commit precisely.
When describing a blob, we want to describe the blob from a higher layer
as well, which is a tuple of (commit, deep/path) as the tree objects
involved are rather uninteresting. The same blob can be referenced by
multiple commits, so how we decide which commit to use? This patch
implements a rather naive approach on this: As there are no back pointers
from blobs to commits in which the blob occurs, we'll start walking from
any tips available, listing the blobs in-order of the commit and once we
found the blob, we'll take the first commit that listed the blob. For
example
git describe --tags v0.99:Makefile
conversion-901-g7672db20c2:Makefile
tells us the Makefile as it was in v0.99 was introduced in commit 7672db20.
The walking is performed in reverse order to show the introduction of a
blob rather than its last occurrence.

When the N-th previous thing checked out syntax (@{-N}) is used
with '--branch' option of check-ref-format the result may not be
the name of a branch that currently exists or ever existed. This
is because @{-N} is used to refer to the N-th last checked out
"thing", which might be a commit object name if the previous check
out was a detached HEAD state; or a branch name, otherwise. The
documentation thus does a wrong thing by promoting it as the
"previous branch syntax".
State that @{-N} is the syntax for specifying "N-th last thing
checked out" and also state that the result of using @{-N} might
also result in an commit object name.

git-clone and git-checkout both invoke the post-checkout hook following
a successful checkout, yet git-worktree neglects to do so even though it
too "checks out" the worktree. Fix this oversight.
Implementation note: The newly-created worktree may reference a branch
or be detached. In the latter case, a commit lookup is performed, though
the result is used only in a boolean sense to (a) determine if the
commit actually exists, and (b) assign either the branch name or commit
ID to HEAD. Since the post-commit hook needs to know the ID of the
checked-out commit, the lookup now needs to be done in all cases, rather
than only when detached. Consequently, a new boolean is needed to handle
(b) since the lookup result itself can no longer perform that role.

When a graphical GIT_EDITOR is spawned by a Git command that opens
and waits for user input (e.g. "git rebase -i"), then the editor window
might be obscured by other windows. The user might be left staring at
the original Git terminal window without even realizing that s/he needs
to interact with another window before Git can proceed. To this user Git
appears hanging.
Print a message that Git is waiting for editor input in the original
terminal and get rid of it when the editor returns, if the terminal
supports erasing the last line. Also, make sure that our message is
terminated with a whitespace so that any message the editor may show
upon starting up will be kept separate from our message.
Power users might not want to see this message or their editor might
already print such a message (e.g. emacsclient). Allow these users to
suppress the message by disabling the "advice.waitingForEditor" config.
The standard advise() function is not used here as it would always add
a newline which would make deleting the message harder.

Currently 'git worktree add <path>' creates a new branch named after the
basename of the <path>, that matches the HEAD of whichever worktree we
were on when calling "git worktree add <path>".
It's sometimes useful to have 'git worktree add <path> behave more like
the dwim machinery in 'git checkout <new-branch>', i.e. check if the new
branch name, derived from the basename of the <path>, uniquely matches
the branch name of a remote-tracking branch, and if so check out that
branch and set the upstream to the remote-tracking branch.
Add a new --guess-remote option that enables exactly that behaviour.

There have been a few complaints on the mailing list that git-clone doesn't
respect the `submodule.recurse` setting, which every other command (that
potentially knows how to deal with submodules) respects. In case of clone
this is not beneficial to respect as the user may not want to obtain all
submodules (assuming a pathspec of '.').

synopsis to alleviate the confusion around the submodule recursion flag
in git-clone.
While at it clarify that the option can be given multiple times for complex
