== Maintainer Note ==

Depends on a merge of en/present-despite-skipped into master.

== Overview ==

This patch changes the default mode for sparse-checkout from non-cone mode
to cone-mode, and marks non-cone mode as deprecated. There is no plan to
remove non-cone mode, we are merely recommending against its use.

The code change is pretty small, and most of this series is about
documentation updates -- to focus on directories rather than patterns, to
explain the new default, to explain why we are deprecating non-cone mode
(the final patch), and to make other related cleanups to simplify the
manual.

Patch 1: Update tests to not assume cone-mode is the default Patch 2: Make
cone-mode the default Patches 3-9: Various updates to
git-sparse-checkout.txt, divided up for ease of review

== Alternative ==

There is one primary alternative to this series: make sparse-checkout error
when neither --cone nor --no-cone are specified (so that there is no
default), and wait until a future date to make --cone the default. That'd be
reasonable, but I had three reason to avoid going this route (note that item
2 means there's little practical difference between cone-mode-as-default and
no-mode-is-default):

 1. git-sparse-checkout.txt has the following huge warning early in the
    manual:

""" THIS COMMAND IS EXPERIMENTAL. ITS BEHAVIOR, AND THE BEHAVIOR OF OTHER
COMMANDS IN THE PRESENCE OF SPARSE-CHECKOUTS, WILL LIKELY CHANGE IN THE
FUTURE. """

 2. If users are unaware of the default change and attempt to provide
    patterns instead of directories, then they will get error messages added
    from en/sparse-checkout-fixes. They can learn at that time to get around
    the error messages by providing --no-cone.

 3. If users are unaware of the default change and provide directories, then
    that's where non-cone mode and cone mode overlap and things happen to
    work. (There is a slight difference in that cone mode will include files
    from parent directories of any specified directory, but that means the
    user gets a few more files in their sparse-checkout with cone mode than
    they would with non-cone mode.)
