Remove contrib/examples/*ab/drop-contrib-examples

There were some side discussions at Git Merge this year about how we
should just update the README to tell users they can dig these up from
the history if the need them, do that.

Looking at the "git log" for this directory we get quite a bit more
patch churn than we should here, mainly from things fixing various
tree-wide issues.

There's also confusion on the list occasionally about how these should
be treated, "Re: [PATCH 1/4] stash: convert apply to
builtin" (<CA+CzEk9QpmHK_TSBwQfEedNqrcVSBp3xY7bdv1YA_KxePiFeXw@mail.gmail.com>)
being the latest example of that.

-These are original scripted implementations, kept primarily for their
-reference value to any aspiring plumbing users who want to learn how
-pieces can be fit together.
+This directory used to contain scripted implementations of builtins
+that have since been rewritten in C.
+
+They have now been removed, but can be retrieved from an older commit
+that removed them from this directory.
+
+They're interesting for their reference value to any aspiring plumbing
+users who want to learn how pieces can be fit together, but in many
+cases have drifted enough from the actual implementations Git uses to
+be instructive.
+
+Other things that can be useful:
+
+ * Some commands such as git-gc wrap other commands, and what they're
+   doing behind the scenes can be seen by running them under
+   GIT_TRACE=1
+
+ * Doing `git log` on paths matching '*--helper.c' will show
+   incremental effort in the direction of moving existing shell
+   scripts to C.

-
-
-DESCRIPTION
------------
-Imports a SVN repository into git. It will either create a new
-repository, or incrementally import into an existing one.
-
-SVN access is done by the SVN::Perl module.
-
-git-svnimport assumes that SVN repositories are organized into one
-"trunk" directory where the main development happens, "branches/FOO"
-directories for branches, and "/tags/FOO" directories for tags.
-Other subdirectories are ignored.
-
-git-svnimport creates a file ".git/svn2git", which is required for
-incremental SVN imports.
-
-OPTIONS
--------
--C <target-dir>::
-        The GIT repository to import to.  If the directory doesn't
-        exist, it will be created.  Default is the current directory.
-
--s <start_rev>::
-        Start importing at this SVN change number. The  default is 1.
-+
-When importing incrementally, you might need to edit the .git/svn2git file.
-
--i::
-	Import-only: don't perform a checkout after importing.  This option
-	ensures the working directory and index remain untouched and will
-	not create them if they do not exist.
-
--T <trunk_subdir>::
-	Name the SVN trunk. Default "trunk".
-
--t <tag_subdir>::
-	Name the SVN subdirectory for tags. Default "tags".
-
--b <branch_subdir>::
-	Name the SVN subdirectory for branches. Default "branches".
-
--o <branch-for-HEAD>::
-	The 'trunk' branch from SVN is imported to the 'origin' branch within
-	the git repository. Use this option if you want to import into a
-	different branch.
-
--r::
-	Prepend 'rX: ' to commit messages, where X is the imported
-	subversion revision.
-
--u::
-	Replace underscores in tag names with periods.
-
--I <ignorefile_name>::
-	Import the svn:ignore directory property to files with this
-	name in each directory. (The Subversion and GIT ignore
-	syntaxes are similar enough that using the Subversion patterns
-	directly with "-I .gitignore" will almost always just work.)
-
--A <author_file>::
-	Read a file with lines on the form
-+
-------
-	username = User's Full Name <email@addr.es>
-
-------
-+
-and use "User's Full Name <email@addr.es>" as the GIT
-author and committer for Subversion commits made by
-"username". If encountering a commit made by a user not in the
-list, abort.
-+
-For convenience, this data is saved to $GIT_DIR/svn-authors
-each time the -A option is provided, and read from that same
-file each time git-svnimport is run with an existing GIT
-repository without -A.
-
--m::
-	Attempt to detect merges based on the commit message. This option
-	will enable default regexes that try to capture the name source
-	branch name from the commit message.
-
--M <regex>::
-	Attempt to detect merges based on the commit message with a custom
-	regex. It can be used with -m to also see the default regexes.
-	You must escape forward slashes.
-
--l <max_rev>::
-	Specify a maximum revision number to pull.
-+
-Formerly, this option controlled how many revisions to pull,
-due to SVN memory leaks. (These have been worked around.)
-
--R <repack_each_revs>::
-	Specify how often git repository should be repacked.
-+
-The default value is 1000. git-svnimport will do imports in chunks of 1000
-revisions, after each chunk the git repository will be repacked. To disable
-this behavior specify some large value here which is greater than the number of
-revisions to import.
-
--P <path_from_trunk>::
-	Partial import of the SVN tree.
-+
-By default, the whole tree on the SVN trunk (/trunk) is imported.
-'-P my/proj' will import starting only from '/trunk/my/proj'.
-This option is useful when you want to import one project from a
-svn repo which hosts multiple projects under the same trunk.
-
--v::
-	Verbosity: let 'svnimport' report what it is doing.
-
--d::
-	Use direct HTTP requests if possible. The "<path>" argument is used
-	only for retrieving the SVN logs; the path to the contents is
-	included in the SVN log.
-
--D::
-	Use direct HTTP requests if possible. The "<path>" argument is used
-	for retrieving the logs, as well as for the contents.
-+
-There's no safe way to automatically find out which of these options to
-use, so you need to try both. Usually, the one that's wrong will die
-with a 40x error pretty quickly.
-
-<SVN_repository_URL>::
-	The URL of the SVN module you want to import. For local
-	repositories, use "file:///absolute/path".
-+
-If you're using the "-d" or "-D" option, this is the URL of the SVN
-repository itself; it usually ends in "/svn".
-
-<path>::
-	The path to the module you want to check out.
-
--h::
-	Print a short usage message and exit.
-
-OUTPUT
-------
-If '-v' is specified, the script reports what it is doing.
-
-Otherwise, success is indicated the Unix way, i.e. by simply exiting with
-a zero exit status.
