Add a flag for indicating an update to a reference requires force.
Currently the `nonfastforward` flag is used for this when generating the
status message.  A separate flag insulates dependent logic from the
details of set_ref_status_for_push().

Advising the user to fetch and merge only makes sense if the rejected

A symbolic ref refs/heads/SYM was not correctly removed with

"git log -F -E --grep='<ere>'" failed to use the given <ere>
pattern as extended regular expression, and instead looked for the
string literally.  The early part of this series is a fix for it;
the latter part teaches log to respect the grep.* configuration.

  log: honor grep.* configuration
  log --grep: accept --basic-regexp and --perl-regexp
  log --grep: use the same helper to set -E/-F options as "git grep"

  grep: move the configuration parsing logic to grep.[ch]
  builtin/grep.c: make configuration callback more reusable

If you remove a submodule, in order to keep the repository so that
"git checkout" to an older commit in the superproject history can
resurrect the submodule, the real repository will stay in $GIT_DIR
of the superproject.  A later "git submodule add $path" to add a
different submodule at the same path will fail.  Diagnose this case
a bit better, and if the user really wants to add an unrelated
submodule at the same path, give the "--name" option to give it a
place in $GIT_DIR of the superproject that does not conflict with
the original submodule.

* jl/submodule-add-by-name:
  submodule add: Fail when .git/modules/<name> already exists unless forced
  Teach "git submodule add" the --name option

"git rm submodule" cannot blindly remove a submodule directory as
its working tree may have local changes, and worse yet, it may even
have its repository embedded in it.  Teach it some special cases
where it is safe to remove a submodule, specifically, when there is
no local changes in the submodule working tree, and its repository
is not embedded in its working tree but is elsewhere and uses the
gitfile mechanism to point at it.

* jl/submodule-rm:
  submodule: teach rm to remove submodules unless they contain a git directory

When renaming orig_args to orig_flags in 98dbe63d (submodule: only
preserve flags across recursive status/update invocations) the call site
of the recursive cmd_status was forgotten. At that place orig_args is
still passed into the recursion, which is always empty since then. This
did not break anything because the orig_flags logic is not needed at all
when a function from the submodule script is called with eval, as that
inherits all the variables set by the option parsing done in the first
level of the recursion.

Now that we know that orig_flags and orig_args aren't needed at all,
let's just remove them from cmd_status().

A test in t7404-submodule-foreach purports to test that
the --cached flag is properly noticed by --recursive calls
to the foreach command as it descends into nested
submodules.  However, the test really does not perform this
test since the change it looks for is in a top-level
submodule handled by the first invocation of the command.
To properly test for the flag being passed to recursive
invocations, the change must be buried deeper in the
hierarchy.

Move the change one level deeper so it properly verifies
the recursive machinery of the 'git submodule status'
command.
