Running "git add" on a repository created inside the current
repository is an explicit indication that the user wants to add it
as a submodule, but when the HEAD of the inner repository is on an
unborn branch, it cannot be added as a submodule. Worse, the files
in its working tree can be added as if they are a part of the outer
repository, which is not what the user wants. These problems are
being addressed.

"git merge-recursive" backend recently learned a new heuristics to
infer file movement based on how other files in the same directory
moved. As this is inherently less robust heuristics than the one
based on the content similarity of the file itself (rather than
based on what its neighbours are doing), it sometimes gives an
outcome unexpected by the end users. This has been toned down to
leave the renamed paths in higher/conflicted stages in the index so
that the user can examine and confirm the result.

Robin reported that
git submodule foreach --quiet git pull --quiet origin
is not really quiet anymore [1]. "git pull" behaves as if --quiet is not
given.
This happens because parseopt in submodule--helper will try to parse
both --quiet options as if they are foreach's options, not git-pull's.
The parsed options are removed from the command line. So when we do
pull later, we execute just this
git pull origin
When calling submodule helper, adding "--" in front of "git pull" will
stop parseopt for parsing options that do not really belong to
submodule--helper foreach.
PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should
never see unknown options or something has gone wrong. There are also
a couple usage string update while I'm looking at them.
While at it, I also add "--" to other subcommands that pass "$@" to
submodule--helper. "$@" in these cases are paths and less likely to be
--something-like-this. But the point still stands, git-submodule has
parsed and classified what are options, what are paths. submodule--helper
should never consider paths passed by git-submodule to be options even
if they look like one.
The test case is also contributed by Robin.
[1] it should be quiet before fc1b9243cd (submodule: port submodule
subcommand 'foreach' from shell to C, 2018-05-10) because parseopt
can't accidentally eat options then.

The previous commit made 'git add' abort when given a repository that
doesn't have a commit checked out. However, the output upon failure
isn't appropriate:
% git add repo
warning: adding embedded git repository: repo
hint: You've added another git repository inside your current repository.
hint: [...]
error: unable to index file 'repo/'
fatal: adding files failed
The hint doesn't apply in this case, and the error message doesn't
tell the user why 'repo' couldn't be added to the index.
Provide better output by teaching add_to_index() to error when given a
git directory where HEAD can't be resolved. To avoid the embedded
repository warning and hint, call check_embedded_repo() only after
add_file_to_index() succeeds because, in general, its output doesn't
make sense if adding to the index fails.

When 'git blame' is invoked without specifying the commit to start
blaming from, it starts from the given file's state in the work tree.
However, when invoked in a bare repository without a start commit,
then there is no work tree state to start from, and it dies with the
following error message:
$ git rev-parse --is-bare-repository
true
$ git blame file.c
fatal: this operation must be run in a work tree
This is misleading, because it implies that 'git blame' doesn't work
in bare repositories at all, but it does, in fact, work just fine when
it is given a commit to start from.
We could improve the error message, of course, but let's just default
to HEAD in a bare repository instead, as most likely that is what the
user wanted anyway (if they wanted to start from an other commit, then
they would have specified that in the first place).
'git annotate' is just a thin wrapper around 'git blame', so in the
same situation it printed the same misleading error message, and this
patch fixes it, too.

Don't redundantly run "git reflog expire --all" when gc.reflogExpire
and gc.reflogExpireUnreachable are set to "never", and die immediately
if those configuration valuer are bad.
As an earlier "assert lack of early exit" change to the tests for "git
reflog expire" shows, an early check of gc.reflogExpire{Unreachable,}
isn't wanted in general for "git reflog expire", but it makes sense
for "gc" because:
1) Similarly to 8ab5aa4bd8 ("parseopt: handle malformed --expire
arguments more nicely", 2018-04-21) we'll now die early if the
config variables are set to invalid values.
We run "pack-refs" before "reflog expire", which can take a while,
only to then die on an invalid gc.reflogExpire{Unreachable,}
configuration.
2) Not invoking the command at all means it won't show up in trace
output, which makes what's going on more obvious when the two are
set to "never".
3) As a later change documents we lock the refs when looping over the
refs to expire, even in cases where we end up doing nothing due to
this config.
For the reasons noted in the earlier "assert lack of early exit"
change I don't think it's worth it to bend over backwards in "git
reflog expire" itself to carefully detect if we'll really do
nothing given the combination of all its possible options and skip
that locking, but that's easy to detect here in "gc" where we'll
only run "reflog expire" in a relatively simple mode.

intentional that "commit-graph verify" doesn't error out when the file

An earlier change implemented load_commit_graph_one_fd_st() in a way
that was bug-compatible with earlier code in terms of the "graph file
%s is too small" error message printing out the path to the
commit-graph (".git/objects/info/commit-graph").
But change that, because:
* A function that takes an already-open file descriptor also needing
the filename isn't very intuitive.
* The vast majority of errors we might emit when loading the graph
come from parse_commit_graph(), which doesn't report the
filename. Let's not do that either in this case for consistency.

Make the commit-graph loading code work as a library that returns an
error code instead of calling exit(1) when the commit-graph is
corrupt. This means that e.g. "status" will now report commit-graph
corruption as an "error: [...]" at the top of its output, but then
proceed to work normally.
This required splitting up the load_commit_graph_one() function so
that the code that deals with open()-ing and stat()-ing the graph can
now be called independently as open_commit_graph().
This is needed because "commit-graph verify" where the graph doesn't
exist isn't an error. See the third paragraph in
283e68c72f ("commit-graph: add 'verify' subcommand",
2018-06-27). There's a bug in that logic where we conflate the
intended ENOENT with other errno values (e.g. EACCES), but this change
doesn't address that. That'll be addressed in a follow-up change.
I'm then splitting most of the logic out of load_commit_graph_one()
into load_commit_graph_one_fd_st(), which allows for providing an
existing file descriptor and stat information to the loading
code. This isn't strictly needed, but it would be redundant and
confusing to open() and stat() the file twice for some of the
codepaths, this allows for calling open_commit_graph() followed by
load_commit_graph_one_fd_st(). The "graph_file" still needs to be
passed to that function for the the "graph file %s is too small" error
message.
This leaves load_commit_graph_one() unused by everything except the
internal prepare_commit_graph_one() function, so let's mark it as
"static". If someone needs it in the future we can remove the "static"
attribute. I could also rewrite its sole remaining
user ("prepare_commit_graph_one()") to use
load_commit_graph_one_fd_st() instead, but let's leave it at this.
