* bc/submodule-status-ignored:
  Improve documentation concerning the status.submodulesummary setting
  submodule: don't print status output with ignore=all
  submodule: fix confusing variable name

The --for-status option was an undocumented option used only by
wt-status.c, which inserted a header and commented out the output. We can
achieve the same result within wt-status.c, without polluting the
submodule command-line options.

This will make it easier to disable the comments from wt-status.c later.

The --for-status is kept so that another topic in flight
(bc/submodule-status-ignored) can continue relying on it, although it is
currently a no-op.

git status prints information for submodules, but it should ignore the status of
those which have submodule.<name>.ignore set to all.  Fix it so that it does
properly ignore those which have that setting either in .git/config or in
.gitmodules.

Not ignored are submodules that are added, deleted, or moved (which is
essentially a combination of the first two) because it is not easily possible to
determine the old path once a move has occurred, nor is it easily possible to
detect which adds and deletions are moves and which are not.  This also
preserves the previous behavior of always listing modules which are to be
deleted.

Tests are included which verify that this change has no effect on git submodule
summary without the --for-status option.

cmd_summary reads the output of git diff, but reads in the submodule path into a
variable called name.  Since this variable does not contain the name of the
submodule, but the path, rename it to be clearer what data it actually holds.

Allow shallow-cloning of submodules with "git submodule update".

* fg/submodule-clone-depth:
  Add --depth to submodule update/add

Add the --depth option to the add and update commands of "git submodule",
which is then passed on to the clone command. This is useful when the
submodule(s) are huge and you're not really interested in anything but
the latest commit.

Tests are added and some indention adjustments were made to conform to the
rest of the testfile on "submodule update can handle symbolic links in pwd".

Users can set submodule.$name.update to '!command' which will cause
'command' to be run instead of checkout/merge/rebase. This allows
the user finer-grained control over how the update is done.

The primary motivation for this was interoperability with stgit;
however being able to intercept the submodule update process may
prove useful for integrating with or extending other tools.

Allow various subcommands of "git submodule" to be run not from the
top of the working tree of the superproject.

* jk/submodule-subdirectory-ok:
  submodule: drop the top-level requirement
  rev-parse: add --prefix option
  submodule: show full path in error message
  t7403: add missing && chaining
  t7403: modernize style
  t7401: make indentation consistent

Many "git submodule" operations do not work on a submodule at a
path whose name is not in ASCII.

* fg/submodule-non-ascii-path:
  t7400: test of UTF-8 submodule names pass under Mac OS
  handle multibyte characters in name

Use the new rev-parse --prefix option to process all paths given to the
submodule command, dropping the requirement that it be run from the
top-level of the repository.

Since the interpretation of a relative submodule URL depends on whether
or not "remote.origin.url" is configured, explicitly block relative URLs
in "git submodule add" when not at the top level of the working tree.
